I think a lot of people are confusing attack animation with animation lock. People complaints were not about standing still to use chaos thrust it was the fact after the animation finished you were bound for 1-2 secs which is pretty dumb. Hell even XI did not lock you down after every ws or spell.

Look at the Coincounter fight The fight its self is simple but tanks can hardly do anything in that fight cause you don't want to be locked down cause you wanted to use a self buff.
