Nerfing high tier characters is not how you balance a game at all.
That is the same mistake capcom has made with its own games countless times and it only caused a lot of useless characters/bad match ups. Back when AE first came out, the twins and fei long were the best in the game and had tons of great match ups and only about two or three characters were able to actually stand a chance if this were based on ratio. But what I truly loved was how tournament players actually tried to find ways around these characters, use their tools to their own advantage, and try to win to move on in the tournaments they participated instead of giving up and letting a character become their
excuse.
Anyways, since the twins were such a problem and there was so much backlash from the competitive scene that they all wanted them nerfed, without any thought. Capcom went along and nerfed the hell out of these characters, taking away most of the tools that made them extremely viable to now semi viable. Fei Long suffered the most IMO after the 2012 patch, which included, for some retarded reason, every character in the roster. But my point is, was this the overall game changer? Did this balance the game in anyway? NO! This just fucked it up to what it has now become an unbalanced game where the current high tiers now have easier advanced options (unblockable, meterless damage, frame advantage) unlike the others, and the ideal balance is still not there since low tiers are a lot more useless than before.
How to balance MK9?
Not Nerf Kabal (Leave him the way he is)
Buff the High tiers very slightly
Buff everyone else and give them tools to help them against their worst match ups
Of course, this will not happen. So I suggest you all step your game up and play the game the way it is. Overcome your worst match ups. You are all more than fortunate that this game got patched unlike fighters from before, where people who actually wanted to learn and loved the game tried there best to overcome skill and match up advantage. Develop the meta game, and do less complaining. NRS is gone.
