This was one of my worries pre-beta, that the AI would just wait to be attacked in small units. I agree that their use of cover and evasion was nice, that raised my hopes for clever AI, but the lack of patrols quickly reignited my disappointment. The first time I went into explore mode, I quickly learnt enemy locations and how best to avoid them - that should not be the case. With random patrols, a hierarchy system that makes smaller units flee and other random things that make enemies feel like a threat rather than sitting ducks would be terrific. I was about to critique MMOs for having packs of enemies clustered in the same spot, but then I realised that most of the time they're placed willy nilly and move about a bit. Giving mobs schedules, responding to the chain of command and perhaps even in-fighting would make them a lot more interesting. ^^
