I think the Evo game lineup was already finalized before most people realized how bad SFxT was. A lot of people assumed it would be the next big thing.
Yes, this was
exactly the case. It was put into the lineup and announced to be at EVO along with the other games. This was in March/mid April if I recall, so the game was
still in its early stages. This was before they decided to do 2v2 though! The ruleset was undetermined for quite some time for SFxT, but it was def. announced in the lineup when the game was fairly young and before all the hate it's gotten.
I'd really like to see the game get fixed somehow, but there's just so many things wrong with it from damage scaling to the timer to jabs it's... just a lot Capcom has to fix. I just don't see them being able to tackle all of those issues before the Vita version comes out. What's more is, people are
still discovering more infinites in the game! Which is crazy.
Bottom line, the more Capcom sits on patches the more the game dies off competitively. And I get there's like a big testing period between patches but just from what they talked about at EVO it really doesn't seem like they're up to date with the community on what
needs to be fixed versus what's not as important. DLC characters, while important, aren't as important as fixing the timer or ridiculous damage scaling.
I really think the game should just be a bonkers combo game, look at TTT2! Same style of game (except 3D obv) and general gameplay, yet its matches look to be pretty fast paced and combo heavy from what I saw at EVO (barring
completely different juggle mechanics than SFxT).
All in all, the game sucks right now and isn't entertaining to watch or play.
