What I'm having problems with, is just too much grass at times. It does look nice aesthetically, but impractical IMO. D:OS1 was much more cartoonish and the terrain was much more "plain", however the battlefield was much more easily "readable".
Also I don't like the new stun-effect, the new fire-surface effect, and the cursed-blessed effects (except blessed fire and cursed water, I guess) look awful IMO... But that's another story.
