Like I said it's an animation that raises the players hands it will hardly cause any lag whatsoever. The reason the other shards remove it is so that you can't see when the cast will come in

the sparkles and flames of spells cause more animation that would cause more lag than this considering you can barley see the hands moving

It's much more than that. When you cast, you change direction. Casting a lot while running creates a skippy effect a lot of the time, and having high ping doesn't help that. I don't know why it happens here though... Probably because we are trying to emulate sphere 51a on runuo
