Indeed, thats why I started this post, there are light attacks that its animations needs to be tunned a bit faster, to compensate its weakness (less dmg and no hyperarmor aka AxeL1and4), or give hyperarmor to the last attack on Light chain.
The heavy ones I think it doesnt need to be changed, only the light ones making it faster, because there are slow ones that are faster than the light ones like the cases, Axe 1H / 1L, 4H/4L .
