Here a few points that comes to my mind after having used and even fought against them:
-They have no upgrades
I haven’t played a full campaign yet, but as far as i know once you have them they are as good as they are going to be. No new weapons for them, no better armor or any new features for them.
-They are not that powerful
Early game they may be a good addition to a squad as their weapons are more powerful than what you have. However your people improve and become deadlier and better equipped, your vehicle remain the same. Also, for how big they are, they are not that durable, they are easily crippled by a few attacks be it factions or the Pandorans. It’s nice that they have immunities to a lot of damage types and effects, but as vehicles go they lack durability and firepower.
-They quickly run out of ammo
For those that have weapons, they don’t have enough ammo to last on larger battles. It’s also aggravating we can’t reload them.
-No secondary attacks
Besides their primary weapon they have no other form of attack. If they run out of ammo or their weapon is disabled, they become useless besides tanking some hits for the team.
-They tend to run though things too much
Destroying obstacles can be useful, but we should be able to tell them to avoid it too. Really annoying when they blow up stuff and take damage from it or when they destroy cover our team need.
-Pandoran melee attacks wreak them
I think it’s silly that an armored vehicle is so easily wreaked by Arthrons bashing at them. Make sense a Scylla be strong and large enough for this, but melee attacks from smaller Pandas and even humans works just as well. I think they should be resistant to melee attacks regardless of how much armor is remaining.
-Sniper Rifles works too well on them
As the game is, sniper weapons are the answer to everything. May not be the best damage dealer, but they work well against anything. It’s especially true against vehicles, we can disable their weapons or any of their parts with 2-3 hits.
I do think they need some love. More health, better weapons, alternate attacks, new unlockable perks. Also heavy weapons should be needed to deal with them, should be scary to take them on with basic infantry weapons like rifles and grenades…
