As I said earlier, with Singleplayer Patch, bots usually spread all over the map, but not always this happen.
For instance, I play in Purple Heart Lane 64 map, but I found that bots path is only left side of the main road or right of the main road, I mean, they are not well balanced and distributed over the map, which would be great if they be.
Maybe this situation occurs, because bots use all the same route to reach a flag/waypoint, and even with the German 88mm piece on the right side or MG 34 on left side, hitting them(US) always, they simply jump to the death.
Bots should be able to take more intelligent decisions, like take cover behind walls, or go prone, instead of run directly to the fire.
