A game can be fun in spite of balance. MvC2 is a beloved game even with its six character meta. But when there’s room for improvement, and the internet now makes improvement possible, devs should take the opportunity to improve as much as they can.

Also, speaking of Tekken 5 - are you talking about the initial arcade release, the rebalanced console port, the “5.1” arcade rerelease, or Dark Resurrection? Because those totally count as patches.
