Overall I support you feedback with some small exceptions.
I would not mess the screen with artorks too much.
and
I would suggest them to follow idea of this gentleman
Of couse number value is a must, but I even like that solid rectangle bars, they just can have different length, for longer bars to represent higher values.
Check ‘T’ and ‘G’ keys. Those 4 levels you are talking about are floor levels changed with mouse wheel or ‘Z’ / ‘C’ keys. Check also zoom by pressing middle mouse button.
That WAS a bug. Now it is correctly implemented. Soldier can’t be ready with Assault Rifle, Grenade Launcher and Flamethrower at the same time. Those 3 ‘ready’ items represent what you have in your hands and attached to your belt. Everything else must be in ‘backpack’ and you need some time (action points) to take it out and prepare such weapon. Btw didn’t you saw in all different videos how overpowered was that single element of design? “Oh I see an enemy there far away. So sniper shot! It is closer, so I will pepper it with some bullets from my assault rifle… Oh it is still standing! So maybe backup grenade from big gun will help put it to sleep.” Soldiers are not giant mechs which have 5 super weapons ready to fire simultaneously.
That is frustrating! I don’t know how they designed it, but it really sucks. Currently I will need to swap all items in ready slots in correct order to maintain order on UI which I want. So in your case I would replace weapon in slot 1, move item from slot 2 to intentory and back again into second slot, move item from slot 3 to inventory and back again into third slot. That is annoying.
