RaptorKarr1 votesWhy Corki for Quinn? owo Seem's like most ADC's lose to Quinn.
EndlessSorcerer1 votesI didn't really have many other good options, so I mostly went with a comfort pick.
However, Corki's ability to waveclear and poke is valuable later and allows your team to group and siege objectives. If your team is grouped, Quinn is far less likely to pick somebody off by themselves and she isn't exactly good in a siege situation.
Obviously, people are going to run off and die alone because it's solo-queue, but ideally you would be able to group and pressure objectives while denying picks.
RaptorKarr1 votesFair enough. My Second choice for Quinn was Ashe cause of her ult.
