True, but you need to move close to an enemy you dont see, armed with an high damage sniper riffle that disables you in one shot.
Also, maybe you misanderstand me. Im not saying is not posible to deal with them. Most of the time you can just ok. But I got 3 of these in half my late game missions. And you only need one you cannot deal with to ruin your day. I had a lot of situations with them that gave me little to no way to counter them.
If you try to shoot them from the front yes, but then go for one of their arms or even their weapon.
By the way, the absolutely easiest way of dealing with them is fire grenades; they will take damage from the explosion, the fire and then running through the fire on activating Pain Chameleon.
Nice, never thought about this, even after such a long time playing 
Just a question: Why you don’t use Infiltrators?
They are not the absolutely necessary to deal with Tritons but they can help a lot also in many situation where you need someone to spot ahead without alarming the whole map. One of them on the team can never hurt.
True, I agree again, but with this caveat. Is not easy to flank an enemy you dont see that fires you on long range. Not say when you find them in a cave with no flanking alternatives.
Also true about grenades. I would say not grenades, but fire grenades and flamethrowers (both mostly short range alternatives against a longe range enemy), also vehicle misiles are very good against them. Regular grenades and grenade launchers will only hurt you making them invisible. And still you will often receive the first shot, and sometimes a second shot if you dont disable them in the first strike, which sometimes you cant. And this is enough to ruin any of your soldiers on too many ocasions.
But we are beating the bush with one thing. And this is it, we can argue nonstop about innumerable things in this game on the same way. The point is, I think for many playstyles that should be viable, and specially for non dedicated players. Some of these situations seem unfair too often, and I would say rightfully so.
Dealing with some of the stuff the game throws at you, can only be done in ways that are too specific and require you to know too much of the metagame, giving not enough margin for different choices or mistakes. Some unavoidable.
Perhaps that is so, but I think also some balance has to be maintained re maintenaining a difficulty curve. If when there are enough ways to deal with a situation already, more are added, it can trivialize it to the point where there is no challenge at all.
And being realistic we need to take into account that resources are limited and that devs have telemetry stats that show them how players are doing against the AI, what they are using, etc. I mean, if I was asked 6 months ago what I really want I would say (and I did 
) “balance the skills”, but ultimately I’m happier that what we got were new weapons and toys.
I did not max the relationship with the faction. I chose to go for the disciples of Anu, so I got the berserker and the priest. Being the priest a bit of a disapointment.
Im aware that there are ways to befriend all the factions. But it was my first playthrough, which I completed after 130 hours, and it was too late when I realized this was viable.
This is what i mean with metagame knowledge. Any expert player will jump imediatly to make specific game choices that make the game incredibly more easy. But there is no way for a new player to know how important this is.
I think that relates to how different the experience is for new players and veteran ones. Not playing in a very specific way on your early game, will make the game really hard. And there is no way of knowing it, if you dont navigate to the forums to know about it. which is something I avoided on purpose to not spoil the game too much for myself.
You can simply recruit one, up on a certain point there should be enough around in havens.
You need to have some diplomacy requirements to do so. They were not available for recruiting to me until very late.
Also I had no idea how important they were. I simply decided not going for stealth as I did not understand the stealth mechanics. Which is another problem the game has imo.
This I can completely agree with, and one of the reasons I wish diplomacy was overhauled - to be much less meta. Like achieving supportive status will all factions ASAP being key to efficient exploration, or to be loved by everyone sabotage everyone, or it doesn’t matter if you are best buddies with Anu, NJ wants to be your BFF too.
Yes, this is one of the biggest problems for beginners. IMO many problems would not even arise if there were more and better explanations.
This is completely true. Also one problem with this is how long a playrun is. I took 100+ hours to finish my first campaig. After this, I already knew a lot on the bad decissions that made my life harder. But not many players will go for a second run after a bad experience with the first.
For example I barely did any steal or sabotage, so I was very underresourced. And despite this, I managed to get one of the factions, occasionally two, to have negative relations with me. I also got my second airship too late. And I was almost half game when I realized how important would be to have more assault teams, I spend most of the game with 2. This was a down spiral, as you need resources to get more ships and assaut teams, but in order to get those resources you need precisely more ships and soldiers.
To train soldiers from scratch took me to literally to the end game, when I finally got 4 full teams. And I had almost no resources available by them, as most heavens were down and one of the factions even refused to trade with me.
Also I realised that having so much experience in XCOM, was really taking me down. Only on the final missions I learn how to effectively fight the hoplites (and It was really fun once I understood them). Also I cannot name how much I missused cover early game due to the XCOM thinking.
Stealth is a big ofender here as the game is really obscure in how useful it is, since only dedicated stealth soldiers take any advantage of it, and if you dont have it enemies seem to immediatly be aware of you, so you may just ignore the mechanic (as I did). Also melee has this issue, I commited a couple of soldiers to it, and never stop being amazed on them being some of my best. But many players will not understand this either.
I had my heavy stand in melee range of an enemy and it remained invisible… okay, it was in the Mist, but still, seeing a heavy stand next to a red column unable to melee was annoying…
Yes, Mist is … special.
Mist repeller helps a lot 
Edit: … or grenades if not available 
I just grabbed the Anu defender Assault and shot it to death from melee range 
(It was early enough to not have mist repeller, and not wasting a grenade unless I really have to that early :D)
Stealth needs a proper UI or just no.
For enemy AI cheat, my biggest problem is about overwatch. As the OW in this game already bad because for an unknown reason, your OW soldier just waits with his weapon down, enemies can see your clone with all the details. I saw so many times just enemies run just at the limit of my OW cone. I don’t talk about the cone, i talk about the range. They are walking in front of the cone but just out of range. So there is no surprise mechanic mostly for OW. It’s even bad mostly, because enemies use different path and they ambush you… For that reason I use mostly cover all the map with the cone which you can do without any penalty…
OW needs so many fixes…
It’s RNG. I did an experiment a while back to see if AI “knew” where OW cones were. I tried out different, same and similar OW setups, saving and loading the game. The AI reacts differently to identical setups, sometimes running straight into the cone, sometimes running into the cone from the side, and every once in a while avoiding the cone altogether. These last ones are the ones we notice and assume that the AI cheated, but it’s just RNG.
It could be a cheat but AI uses that randomly and different by positions. If you just OW everywhere then enemy would go in… if there is options, AI would use go in or not as it calculates all the movements of all AI in the map… I don’t say they always calculate OW but most times if it’s open mostly, they are just move one step away from the cone.
So I think they know it but they don’t use this info everytime. but who knows…
I think it depends on the AI of the enemy. Tritons appear the smartest. If they spot you but don’t perceive a clean LOS, they go back. While Arthrons don’t really seem to care.
@oSiyeza just to confirm - Sirens definitely pay WP for mind controlling PX operatives. Just checked: Harbinger MCed my Heavy who had 8 WP, and she lost 8 WP.
