The correct answer here is that as an individual game and fighting mechanics - SF4 > Blazblue
However when you consider that SF4 is the 30th SF game and that Blazblue is the 1st game for that series. - Blazblue > SF4
I guarantee that no one here played Blazblue long enough to say "mechanics are broken" or that its unbalanced(including myself)...so people saying this really need to back up their claims.
