This is a very good point.
Seen from the other perspective, to be consistent, they would also need to get rid of enemies animation locks, which means we'll have to say goodbye to avoiding most enemy TP moves.
Or we accept them as part of game design, once the adjusted server lag makes animation locks look less terrible than they are. I agree tho that they could keep animation locks for the most powerful moves, not for every single selected ability (animation lock on self-buffs makes little sense).
