Irelia's Ult is useless against everything but minions. It needs buffing.
I'm sure I'm not the only one who has noticed how little damage her ult deals. After more then two years of owning Irelia I've found that there is only two reasons to even bother using her ult. One is to clear a minion wave and heal up quickly. The other is just to throw it behind you as you run for your life with the enemy champion chasing you. Why it was nerfed so bad I will never understand. I mean its an ult that does less damage then basic attacks half the time now. Can it even be considered an ult anymore? It's more of a long cool down poke.
