was playing a botmatch on the brother's map and my team had cleared all the way to the valor flag on the right hand side of the enemies base but the AI rook proceeded to try and tear the trebuchet and artillary tower down, but they seemed to be invincible so he stood there doing nothing much, then all of the minions that were coming from the 2 right hand portals stood there and tried to take the towers down too, with no effect.
When i finally made my way up there after noticing it, there was such a mass of minions there that as soon as i capped the flag they just steamrolled the rest of the towers on the right and then killed the citadel in seconds, yet the AI rook was still standing there looking gormless. this imho is exploitable as you could let it happen and when sufficent forces are at the towers just grab the flag and the enemy base is history. as the flag had not been capped no enemy demigod seemed interested in killing anything up there,
During this game also i noticed a few priests get stuck in empty air over the gaps near the cooldown flag on the left, and when i say a few i mean 7+ so if i was looking like getting low on health i would just walk up to them and get a free full heal.
also during this game i had unclean beast running into nothing a lot when trying to pursue enemy gods in essence being denied kills.
