So they took away her only two real combo starters (*b~6a, and 3c), took away her boring loop, which nerfed her damage output, butchered her already bad defensive game by nerfing her CA and taking away the knock back from her hex-edge (which was the only move that gave her any type of real oki game), and with the change of CA taking away primers, even if u do get it off, your still hurting yourself in the long run.
Now even though the new corner combo options do look fun, and that the game is still early to make any precise judgment, tao right now looks like the worst character in the game.
