The warehouse fight is already insanely difficult without these chuckleheads doing everything possible to screw it up: they abandon their easily-defensible position to run into the open and get one-shotted by sniper assholes, they run across flames and caltrops placed by the player, and they use adrenaline shots at the beginning of an extended battle which ensures they will be useless and fatigued for most of it.
Now, maybe fixing their AI to make them less stupid would be a difficult task. But here's a very simple suggestion to make them suck less: take the dang Adrenaline Shots OUT of their inventories! Then they will not use them, and they won't be FATIGUED and useless for most of the battle!
