ULTIMATE Marvel vs Capcom 3...!? FUUUUUUUU-

[SKELTON S. SKELETON]

Actually, given my experience in arcades (which I have a lot of!) If there were two even competitors, they fought evenly. If someone cheesed a round, they usually didn't come back for a second.
All of this victory talk is pretty pointless though, because ultimately if someone becomes a notorious lamer people are going to find out.
Like if I used a Wesker - Sentinel - whoever team against tyvon and just mashed SP with sentinel, I'd expect him to tell people.
