I hope they do better in armor customization. What I mean is being able to change color schemes, more mask options, material type, etc.
I, at least, want the ability to change armor color. Way too many times have I made armor sets that WOULD have looked good together if the colors didn't clash like two knights in a jousting match!
Edit: I also hope they don't make enemies spawn/ambush at the same locations constantly. Every time I cross that bridge outside Gran Soren at night, cue the skeletons. Every time I arrive outside the Witchwood, there's the same pack of wolves. I'm not against some reaccurrance, but I would like more randomized/unsuspecting interactions. That way I never REALLY know when I'm gonna get into a fight, or stumble upon an NPC.
