Ono can stay the hell away from Marvel. Give Nitsuma that much budget, time and stuff he can make a superior game. The Marvel dev team did a great job with Ultimate overall especially when you see where it came from in Vanilla (which people easily forget and shut off from their minds).
Also if you are talking about balance mistakes made for Vanilla... come on now. They barely knew anything about the game and what it would end up being meta game wise and how strategies will develop. You can bet your ass there is going to be some broken shit in SFxTekken coming out the gate (maybe there already is). The important thing is that they acknowledged most of the balance issues and fixed... not go on some agenda of randomly buffing new characters to god tier level so they make all other characters obsolete just for the sake of competitive integrity (*cough* Yun/Yang *cough*).
Just for the record, top 10 best things fixed from Vanilla:
1) Phoenix - Enough said
2) Meter gain nerfed. No more build 3 meter in one combo and LVL3 every character on the opposite team.
3) DHC glitch - Enough said
4) Major X factor nerf on XFLVL1 with minor ones on XFLVL2 and XFLVL2 with additional minimum scaling nerf. You guys have easily forgotten Wolverine running through a character like hot knife through butter and still have half the XFLVL1 left for the incoming next character.
5) Removal of fully invincible assists. Good fucking riddance.
6) Berderper Slash - Enough said
7) Hammer time - Enough said
8) Air dash change - I originally didn't like the change now I love it. Definitely keeps the air dash characters less brain dead and makes zoning much more viable.
9) Majority of characters buffed - That's how you should be going around balancing Marvel.
10) Assists now scale properly in combos
I still don't like mashable hypers, TACs (didn't fix it properly I feel) some of the buffs to the S tiers (*cough* Zero, Wesker & Dorm *cough*) and some of the nerfs to characters who were fine before (She Hulk).
I laughed my ass off at this
