Glad to see grabs reverted! While easy whiff-less grabs with dash macro are gone, players can still get them by plinking H>M similar to UMvC3 (though here they can be activated mid-dash).
Plink H > L/M + Forward/Down-Forward, then Back/Down-Back will let you approach with a parry if they hit a fast button, grab them if they're blocking, and still gives a chance to block any slower buttons they may have pressed. Other option selects I'd mentioned on the previous update's page are still present, but restoring this OS restores favor to the player on offense while still leaving an opening to get caught by slower or delayed overheads/lows.
