NM SC2 2K was +3 on hit, just FYI. Raph is the only character that had +5, average 2K on hit was +2~+3 (soph/cass, for example)
As a big supporter of SC2, I'm actually going to surprise you and say that I agree with pretty much everything here. Except, of course, the lows, which has always been my biggest complaint with 3 and 4. I fell in love with a game that gave all it's characters viable mixups, and that's where my heart belongs.
I also kind of see the oki complaint from both sides- I remember playing a match where a local player was running a simple NM 3B/Hell Sweep mixup repeatedly on a downed opponent and shouting "THERE'S NO OKI IN SC2" while doing it. It's still there, you still don't have access to certain things and there is a delay on getting up, but SC2 is incredibly, ah, friendly to the downed opponent. There's no shoryukens though. That's a plus, isn't it? :)
SC2 is still the only game that makes me feel like every character can win in tournament-- because they did. SC3 and SC4 never had a moment like Hayate Yun OCV and SC2 benefited from it's top tier character only being slightly more ridiculous then the rest of the cast. When SC5 comes out I hope it can have great moments too, regardless of what character is on the screen. That's all I want.
