Enemy behavior for some reason feels like it got downgraded from beta to full release. I distinctly remember enemies actually making an effort to go for my back line, ranged enemies occasionally going for my back line, or threaten my ranged characters standing too close to my front line. I never observed certain enemies casting Channel Negative Energy with no valid targets nearby during the beta either. Could be a side effect of myself picking Normal difficulty for now.
Also that orange snake pet is super distracting. Should be shrunken down to the size of a cat or something.
