Animation Cancelling
So I think it was about a patch or two ago that they fixed Riven's Q animation so that it would automatically cancel if you went to do an auto attack roght after, so why not also apply this to other champions? An example is Fiora's lunge, you can as of currently animation cancel with her Lunge so that you get a smooth harass combo out but the timing on it is a bit hard to get down (same with Riven's Q before the fixed it). I believe Jax is able to animation cancel with his Leap Strike but only if he has enough attack speed. Anyways if Riot could implement the same thing they did with Riven to a few other champions then it would be a nice minor buff to the champions like Riven.
