When fighting Twintania for example if Stoneskin lands WHILE Twintania is casting Death Sentence it will not register as being on the tank and they will take full damage.
This also happens with stuff like Hallowed Ground not going off when the button is pressed but the cooldown still starts.
Is it possible you guys that Square Enix could fix these issues where we don't have to wait on animations for instant cast abilities to go off and making spells like Lustrate and Stoneskin get recognized by the server quicker ?
