It didn't just do that though.
In many matchups, in fact, the opponent can't really do anything against Viola at range until she decides to come in. When she comes in, she will guess with her ball, and you'll be forced to block. Then she will come in with her claws, and you'll be forced to guess again. Then she will retract her ball (which you will block or get hit by, putting her at frame advantage either way) and then put you into another mixup, forcing you to guess.... again.
Now I'm all about giving people frame advantage so they can force a person to guess three times in a row, assuming it comes from a specific move or setup that can actually be reasonably avoided. Frame advantage makes sense as a reward for doing something right, be it from environment, reading, or spacing properly. With Viola it cannot be reasonably avoided and that makes it bullshit.
Furthermore, all of her guesses result in fucking ridiculous amounts of damage, which is completely unreasonable for the ease at which she can apply the situation.
Just Guarding her is worthless, and the only real way to break pressure is to use meter to GI her damn ball -- which of course, isn't an option right off the bat. And even when you get the meter to do it, spending meter on that means you can't play your character to his actual strengths AT ALL during the match. It's a ridiculous handicap.
Because of the insanity of this kind of fighting, plus the removal of safe movement, SCV quickly devolved into Guess Calibur V. That is the primary reason I stopped playing it.
