Marie Rose isn't a 9 frame jabber thats plus or neutral (which is effectively plus for most of the cast) on every thing.
Pai is set up in DOA so that every action allows her to continue attacking, and to hell with whatever the enemy wants to do because it can take a backseat to her demands. Stuns after throws, okizeme pressure after hard knockdowns, advantage after block, whatever.
She doesn't get a lot of guarantees, but considering she dictates absolutely everything else, why in gods name should she?
