Last time i checked you didn't use a block button for SF either and even in SF you had to block crossups normally. Hell in SF4 there were unblockable crossups lmfao... 1 frame to block it.
Lmao.. I don't know about that one. R2 block button doesn't block high low for you.. you still have to block correctly and damn near every char has a safejump high/low option after EX. Cooldowns are there for a reason especially when the damage for the game can get high and since EX moves grant...
