So i got another thing that is realy bothering me in late game. Collision Boxes.
Engis block everything, getting adjacency bonus on a t3 land fab is a big nogo as they block every unit that may come out of it etc.
So what if there wouldnt be an engi or T1 PGen collision box and every unit could simply travel through. It would reduce the bumpage and improve pathfinding in bases. I dont know if this has any unwanted side effects (i.e. building multiple pgens in the same spot) but stacking engis are more easy to kill so theres the biggest no go out of the way
