Lack of variety gets annoying.
It's actually worse than Tekken 6, which I thought it was impossible.
Oh, and lag OFTEN ruins combos, mostly because I'm not used to it yet.
Yeah a lot of the same character, par for the course. As far as the lag goes, I don't think it's any worst than what I'm normally used to, it's just that MvC is very execution heavy so it just feels worst.
