I agree with you Eric 100%. Those blue and purple caves are hideous in every respect...even made worse when someone throws a speed buff on you, and you get stuck in every frackin corner because you overshoot your turn. :(

Though Villian side, those maps are laid out a little more interstingly and expansive. Though those designs don't carry over on Hero side until you start hitting Tasks Forces.

Anyways...yes agreed, the game needs more new inovated maps (without making them Black Rock Depths in WoW.)
