MK, a button masher? PAH! ... when UMK3 hits the XBLA we'll see how well your button mashing holds up
while it's quite obvious that truly skilled DOA players like yourself can conquer button mashers any day I'd say that DOA is more of a button masher then the MK series is (at least more so then the old 2D ones, I might agree with you about the 3D ones though).
When it comes down to it ANY skilled fighting game player should be able to wipe the floor with a button masher no matter what the game.
