To me it`s more about balance than clones (though I`ll never understand why over 80% of the cast has a meterless invincible reversal wtf) KOF has clones galore and look how that turned out.
This game is exactly why I retired from Capcom fighters. Unbalanced gameplay with copy and paste characters. Not to mention lack of innovation/progression mechanics wise. Such a shame because I had hope for Street Fighter, but alas....
