Bison's entire gameplan is block or throw. He has no mixups. He gets no throws without ticks. You CAN tickthrow in SFIV-series. Because the throw system is designed for it. At the bolded: Lol. Purple throws are throws executed on an opponent during blockstun or hitstun. No waiting for recovery. Just DO IT. Against people with slow reactions or people who weren't paying attention, Hakumen ate WELL off that shit.
Throw breaks reset into neutral. Why are people so against a game having neutral? It's like people want neutral, one mistake, combo, setplay, Let's Rock. I don't see how it could weaken the normal throw game. It's 1-2 Frames. I can tell you right now, I can't react to a damned thing in 1-2 Frames. I'll only ever get a throw break if I coincidentally went for a counter throw. If I don't get a throw break, I was either late and got thrown or I was early and got a throw. Throw animations are ALL long enough to react to and combo off of, either with meter (Slayer, Ky, etc) or without meter (Millia, Leo, etc). So, if one of us wins the throw/break situation, either of us will be able to capitalize on it. If it was 13F like in Blazblue for normal throws and 27F (HOLY SHIT) for Purple Throws, I can see it weakening the normal throw game, but with 1-2 Frames, it'll only ever happen if you were going for the throw anyway.
