Sion Held by Hatred

Hi - can you please look into the possibility of adding a cooldown of 1 to Sion's Held by Hatred after he dies? It is unbelievably frustrating and unfair when you kill him once, and then he revives himself, somehow gets to take the very next turn, and immediately gets to use held by hatred AGAIN. I guess another option would be to reduce his revivable speed so that he doesn't immediately jump ahead of everyone else remaining in the battle. It's just an ability that makes no sense to me, the revive is powerful enough, and it starts with a 15 cooldown, so why is it at 0 when he is revived?
