Bryan... Roll should beat Shake and all parrys. Why? Because the attack hits the lower part of the hitbox where the active parry frames are missing. Lao's "roll", a normal by the way, is a kick that comes down on top of your head. Stryker's "roll" is an attack where he swings his baton upward. See the difference? Besides, Mileena's B3 loses to parries... someone explain that one.
You're a cool guy and all, but seriously man? How many times must we hear the "REO 2nd at EVO" argument? He's one of, if not the, best player right now, and people weren't ready for Mileena. Bad combination. Michelangelo even came up to me after beating me in losers finals at SJ5 and said, "Zero, you probably would've beaten me if I hadn't trained against her with Reo at evo".
As for you Doctor V... yes the move would be stupid. Why? Because it's a near full screen low combo starter. This means you'd be crouch blocking at all times. U4 would be free. Throws would be free. B3~roll/B3 EX roll would be a blind mixup. B1,4/B1~roll would be a blind mixup. See the problem? With everything else roll does, this would be far too much. Mileena would be made into a brainless scrub character. No one wants that.
Also, please read the threads already here next time before making a new one. Nothing against you, but this is probably the third discussion about roll being made a low and why it's not.
*sigh* This is why we need character specific mods. Someone close this thread please....
