Nerf Irelia's passive attack speed and bring back the shield penetrating mechanic
The addition of dealing 300% damage to shields was actually a really good mechanic. I don't know why Riot removed it, before she was nerfed this mechanic wasn't broken at all, it was unique and was useful. The most problematic part of her kit is that attack speed spike she gets early game which is not balanced. At Level 1, the bonus is 40%, that's literally Lethal Tempo on a passive that can be refreshed just by using auto attacks. It's not even funny, I hope all of you know that she can gain practically 100% bonus attack speed at level 1 if she takes Lethal Tempo, gets 5 stacks of passive, takes 10% attack speed quint, and buys dagger.
