I'd love to see some non-aggressive enemies, or critters even. I know that's sort of a WoW thing but I loved seeing critters in that game (not suggesting they invented the idea, just the first I think of with all them squirrels and sheeps lol).

In 1.0 there were snurbles that would cast some white magics on you.. Was a pretty cool touch.

Also wanted to add I too noticed that everything was aggressive, most apparent when I aggro'd a deer in the great forest and I was like "really..?" lol. Not game killing, having loads of fun right now, but a touch of passiveness could add a nice level of diversity that seems to be missing.
