I voted yes.
Generally, shes a confusing character that takes good reactions, predictions or spacing along with a good deal of knowledge about her to beat. Although true of most of the case, more so for her.
Given that, she should not be doing this kind of damage.
IMO, these are some solutions:
Put B+K BE back to its original damage, pre-patch, or, making it not juggle aerial opponents. I feel the first retains as much of Violas style as possible.
Make 6A+B not cause as much stun, or cause none at all, or only work once. The latter wouldnt change much, because you can loop B+K BE without multiple 6A+Bs. The first would still allow for 6B+K wake-up afterwards, which i think is acceptable.
Fix 2A+B, make it deactivate when youre hit.
Back throw causes crouch state until recovery. I cant think why it doesnt already do this.
With those 4 areas addressed, youre looking at a Viola who can either pour 2 meters into a combo and get about 170 out of it... or one who cant extend her combos for as long as before, reducing the damage with it.
With that, id say shes still as tricky, but beaten easily with the right strategy providing the Viola doesnt adapt... like a SC character should be ^^ ...no more touch of death.
