auto reply/learning how people talk and predicting automated responses
mana efficiency/clerics learn mob dps, group "tankability", and predict which heals are better suited for the immediate situation
mana efficiency/DPS casters, ability to better make use of your damage spells, or conserve mana.
better pathing/ more human like reaction to situations (IE instead of /stick !front at 98% health on a mob, one character can learn that it can start attacking earlier on certain mobs because the tank can hold agro)
better pathing/ machine learning could help predict better pathing for MQ2Nav, even i have problems with it getting stuck on a log in the middle of no where or something with a weird hit box every now and then.
again I don't know how feasible any of these ideas are. I was just curious if that was something that could be done. Appreciate the Responses.
