The most balanced ADC

not Vayne

I would say Varus at the moment.

Decent laning phase, with his insane Q range. Great team fighter due to his crazy damage and ultimate. All while being insanely weak to being dove on (how all AD carries should be).

Probably Koggers. He's got great damage, but you kinda got to land it.

I'd agree with that and say Varus is definitely pretty balanced right now. On the other hand, I'd also put a vote in for Corki.

Many would probably disagree because he's played a lot in competitive, but I wouldn't say he's particularly strong or one of the OP picks. I think he's just a old reliable who still has that benefit of spiking from one item.
