I would love to have a feature to turn off animations. For instance I play a Promethean mage and I have my Wyrmling out. I want to walk away from the battle to get range to cast fireball on the mobs it's occupying. I have to wait a few seconds every time I want to move a single space while the battle animations for the pet and the mob play out. It's annoying to me and would love the option to turn them off.
I don't think it has anything to do with a synching issue in the code, it's just that everything takes too long. You need to wait for your own animation to finish, then you need to wait for your pet's animation to finish, then you need to wait for each individual enemy's animation to finish...taken together it just adds up to too much time spent waiting to be able to take your next action.
