The slaughter house would of been nice in mka with a new hazard buzzsaws that did minor damage if you bumped into them. yin yang island was cool but did not make an reapearance. the chamber of artifacts was neat to but was also not in mka.

arena's from mkd that was also in mka was falling cliffs, sky temple, foundry. the arenas i liked felt very limited and could of been expaned apon. what arena's that you liked from mkd that did not make it into mka.
