Have you downloaded the Windows EPB 5.3fix and do you have other plugins installed? The bots don't aim high with some weapons they just don't wait enough for the recoil to come down and thats the reason they don't hit. The waypoints editor work good and I think the bots follow paths well. Anyway all this reported maybe are bugs but... I don't have time to develop EPB so there will be no fix soon, I'm sorry.
