why must we squat everytime we use an Instant Ability.

Um...

I've heard of faster combat pace, TP revamp, removing directions from combos, but i haven't seen any official wording about removing the actual animation lock from eg. using self-buffs.

Could someone post some solid evidence on this matter?

If you watch Producer Live Letter you can see Yoshi moving while using weaponskills.

edit: actually I think it was another video with battle gameplay where that was more obvious >.< can't remember which now.
