First of, in the replay it doesn't show if you transformed or not if you do the animation cancel, so someone could just tap B after the transformation hud apears and not try to do the animation cancel and we would never know. It may be necessary to record the live match or show proof of transforming.

Second of I remapped the skill leveling buttons to J, K and L and press B+J+L to up the Q and E at the same time, this makes it much easier to animation cancel and makes transforming two skills at the same time possible.
