Okay I know this is none of my business, but you guys play JOHNNY CAGE. A character that can completely deny wake ups + get free blockstrings and frame traps for it. So why the hell would you want to allow them a wake up just to trade with EX nut punch when you can just regular nut punch into pressure? lol
In my opinion, the only characters in the game who could potentially benifit from this kind of pseudo OS are:
-Scorpion (EX spear)
-Rain (EX roundhouse)
-Skarlet (EX dash)
-Kenshi (EX up slash)
-Freddy (EX Sweet Dream, NMS, tele, x-ray)
-Sonya (EX cartwheel)
-Stryker (EX baton > reset, X-ray)
-Shang Tsung (EX soul steal)
-Raiden (tele, EX vincinity blast, X-ray)
The other characters have either better options or not a good enough EX move/X-ray to be worth the trade and the meter.
But don't get your hopes up. Like I said in my initial thread, I tested this to death with a lot of characters and I just can't seem to find good enough setups to cover all scenarios (immediate wake up attack and roll back into wake up attack). Stryker has a move that gives him an untechable knockdown so he doesn't need to worry about the roll back possibility because... well they just can't roll back.
Anti-teleports OS are more realistic imo. Maybe JC could buffer a reversed EX nut punch during some of his string gaps. Something like that. But the Anti-wake up thing is just too character specific and spacing/timing specific to be reliable.
