I looked over the Wiki. Why is every special a QCF or QCB move? And why are the supers EX motions? That kinda' turns me off. I like the look of Painwheel though. But the aesthetics and now shallow controls turn me off.
Cerebella has specials with DP motions and a super with a 360 motion.
Parasoul has charge b~f/d~u specials.
Regardless, execution barriers are not an indication of a fighting game's inherent depth; that's just your personal preference.
