Why? I reckon the MK controls look great. It's about time it became easier for everyone to rip out the killer moves, not just those with nimble fingers.
I remember playing SFII with my bro years ago. It was always frustrating whenever I anticipated his moves and tried to counter only to realise that what I wanted to do didn't actually happen - consequently, he normally kicked my butt.
I think controls like in MK Armageddon even out the playing field in terms of dexterity. Then the game really becomes about outwitting/outsmarting your opponent.
