This would be a simple yet powerfull improvement for the AI. The same should apply for trenches, the AI should not go beside, atop or around the trench but inside the trench. That is what they are for.
(And if they would not change cover in like every 2 seconds would be also nice)
They were patched a while ago to be much better at that, and they are compared to how they were before.
Me watching my squad suddenly leave the 3rd floor to go out in the street for no reason and get killed
only if there are cookies! 
It seems like some squads are 100% ai. Half the players at the end of the game only get 10 kills in invasion mode. It’s crazy
Yeah, some are suspiciously bad.
1 thing i noticed is that most of the time, when the only engineer in the squad starts building something in the house all run out because the building noise and the dust formation.
If the engineer builds it outside the house, all run out to watch him building.
Amusing behavior 
but also very annoying. 
after few moments in the game squad mode turns quickly to lone fighters lol !!!
