It's particularly funny because they could easily copy the way the ping correcting tools work. To be clear, they don't actually change your ping. What happens is animation locks are communicated to and from the server. Your animation lock doesn't "start" until it gets a response back from the server for you having done the action. The way the ping tools work is that it measures your ping, and then subtracts that duration from the animation lock, thus simulating a zero ping environment (or 5-10 ping depending). So, SE could fix this by either A) Doing the same ping check and adjustment or B) Just having the animation lock start AS the action is communicated to the server, rather then AFTER
