Anywhere from 5 to 15 bots will stay put in Dun Baldar South bunker which effectively makes alliance lose all AVs dude to horde gaining a 5-15 character advantage.
As a player the only way to mitigate this huge disadvantage is by either training horde bots (running away mounted while aggroing a bunch of characters to just run around while your guys can finally push) or cap objectives further behind aka. back-cap.
Preferably bots should just try to zerg the opposite factions leader with maybe the first team going for graveyards and/or towers which the real players then could help them with to push over equilibrium.
