You didn't really read/understand Tao changes or impressions, did you? The prove of that is things you said like "She stilll has has speed, normals and still dance around her opponents". She CAN'T dance arround her opponents like she could anymore, they changed her drive to a point that if you don't do a follow up while using drive (this means using ~A/B/C/6 cancel), she will stop mid air and fall to the ground and her drive has more recovery now...that means she doesn't have crazy mobility anti-Lambda/Tager now. The real problem about the combos is not the damage, we are pretty aware that everybody in the game had damage nerf, the problem is that she doesn't have any useful laucher anymore since 3C doesn't cancel in drive and now her drive has same move proration, making combos like 5B->6A->JC->2D~B no good anymore. They even nerfed her 6A that wasn't that great as anti-air (not great as Ragna's 6A for example) in the first place.
They didn't nerf only her damage or combo, they nerfed her mobility AND she still has a pretty weak defense (9,5k HP, 4 primes, no reversal, they nerfed her CA that was one of the only defense option she had). Not only that, they didn't gave ANY useful buff to her, you can read all loketest topics that you won't see one real buff that isn't useless shit, only nerf after nerf (pretty heavy nerfs). Also if you read the character impressions, the guy says things like "endangered species" and "you could see the despair in the eyes of Tao players"...those are pretty heavy things to say about a character.
Don't try to comment about other characters if you don't even understand what happened to it.
