No it's not. having a roll setup is only good for characters with good options after that roll. Terry's options are better without the roll rather than with it and as prevously stated it's not worth the risk at all. first of all its a a hard knock down meaning Terry is right next to a downed opponent and has to wait until they are about to rise to even make this work. and all the time he is wasting could be uses for safe jumps, mix ups, and meaties.
2. Terry's jump angle after a delayed roll doesn't let him do anything special. doesn't have a good cross back over like beni no command grab to set up if you guess the wrong side like clark or shen he has nothing to make this worth while. Your options are baiting a reversal or well applying wake pressure, but these are all things that could have been done without the roll and done more effectivly.
Ambiguity of which side your opponent is on after a roll makes it difficult to block the right way. If timed correctly, you even stuff grab attempts. With d.B, d.A, d.C, you have a pretty easy to confirm combo if they block wrong. If they block right, you'd get the same type of pressure you would if they'd blocked the cross up.
You're saying your options are better, but you're ignoring your own options weaknesses that share the same problems. For you to cross up ambiguously, you'd have to step back. Terry has a hard, if not infuriatingly difficult time faking a cross-up. So you're left with an easy to see frontal jump in our a slightly harder to read front cross up. There is a possibility to cross up hit someone and land in front of them, but that's just as difficult. If you're going to safe jump in front of someone, and they block, that's no different than the roll set up.
Meaties work when someone's not blocking. On a knockdown, if someone is doing a meaty, most people have an invincible reversal which beat meaties. The fact you have to telegraph you're doing a meaty that's not a 4F move like d.B or d.A means that's dangerous. If they do reversal, you just got hit and in Mr. Karate's case, got hit with a 400+ point dmg combo. If they block, you're back to square one just like the roll set up.
If you're trying to mix up...Well, what mixup? Terry doesn't have high-low mix ups that don't cost meter and the only move is EX crackshoot. So why even mention it unless you HAVE a mixup setup after crackshoot. Also like to mention that the ambiguous roll IS a mixup because you can go low from either side of someone.
So although I respect your opinion, I'm curious why these superior options are so superior.
