Bluntly, they fully deserve the disrespect. This rule makes the DoA competitive community look like a bunch of crybabies, while simultaneously drawing attention to the fact that DoA has lots of overly sexy costumes. As I said, I fully expect a massive upswing in the use of sexy costumes in offline tournaments as a direct result of this.
Nah. It is simply a gesture to make the competitive scene more inclusive. The tourney players won't have too much of a problem with it given that DOA's competitive scene was in single digits for a while.
