As someone that has played this game since its release, I must say I have noticed an obvious decline in playability that is, quite frankly, disgusting after all the money I've put into it. Once you reach a certain point in the story, your recovery time for ki and to attack is cut in half and that of your enemy is doubled. It's quite obvious and very annoying. This was never a problem before, now I have my maxed out characters getting one shotted because of an imbalance in the algorithm.
