I all read from ppl complaining about the animation lock was a QQ because they got cought on the cracks, and that wasn't caused by ani-lock but from lag.

If you did that fight, you would know that, you would have goten hit by that second erruption on 13 nails.

and they've made a whole new server structure now, we have the UI client side now as well.
So i don't see any reason as why not have a working animation lock that can make the visuals more engaging and also make you use a bit more strategy in battles and not just spam spam spam
