They've still done nothing to alleviate jab pressure. Gems are still a horrible mechanic. I still hate the disc locked characters. I abhor the existence of autoblock/tech. the timer is still way too fast. I'm reluctant to throw any more money at this PR disaster, and it doesn't look like they're actually addressing those problems with this update.
One thing's for sure. Even if they do fix those problems, its reputation is completely ruined. One horrible design choice after another has kept people away from it, and it's practically beyond redemption. I watched the SFxT tournament for the 25th anniversary, and I still couldn't get excited for the game.
