Can we talk about Corki's passive?
Okay, so, for a champion like Corki, his passive is underwhelming. I can understand the powerful Q. I can understand that W. I can understand the damaging (armor reducing) E. I can understand the damage stacking R. But this passive doesn't strike me as something that Corki should have.
The thing I'm saying is, I don't see much difference in his damage as I do with other ADC's. He gains 10% worth from his AD to deal "true damage" to enemies? I kind of want to know, why does he get a passive that can support his abilities?
I suggest that instead, he gets bonus 20% AD for every bonus AD. This will not only help him more, but it will: effect turrets, give bonuses to his Q, E, and R, and it should have a counter to show its bonus amount.
If Corki were to get up to 300 worth of bonus AD, or more, he'd get 60 bonus or more worth. Totaling to 460, or somewhere around that amount.
