Though I've not finished the game yet, I did notice that the AI's intelligence and aggressiveness can be controlled in the difficulty option settings... for those saying that it was very silly, what setting were your enemies on (I'm mostly curious because I'm only a little way into my fresh play through now that the game has released)?
I played on Scavenger Mode, which is a step above Authentic and enables the deadlier AI. I am currently doing Cataclysm mode but I don't see a big difference and honestly I kind of just got bored and stopped playing.
Even on just Authentic mode - without the 'deadlier ai'- the enemies should use AOE spells sometimes, or any spells really.
