Right now the lords and heroes of the AI randomly put points in things and its just awful. All of the time the wizards have only their starting spell and lords their tree specs are all over the place. When you confed lords you can see how bad they are using their points. The should have a few set build specs that they go for and recruit to synergize their army recruitment.
The AI is awful right now.
Really annoying to see an enemy hero on the campaign map with great items on them but they are just assaulting garrisons of random towns when the AI should transfer those items to other characters..
AI doesn't know what to do because you left it behind.
