@Riot: Regarding the Quinn changes on PBE
First of all, I was a Quinn main (ADC) for most of season 4 (over 200 games, 60% winrate, 5 pentas). Second, I do not have a PBE account and have not and will not get a chance to test these changes myself, the following is purely speculation and my own opinion.
I think increasing her attack range is going to make her even more toxic in top lane and even mid lane. Quinn already stomps most matchups, I think this change would be unhealthy for the game. Even with the movespeed nerf, I don't think she will have trouble keeping distance with her Vault, and she will likely have BoRK and her ult to get away most of the time. Trading movespeed for range is not what she needs. To fix Quinn, she needs a reliable auto attack, which isn't so easy to cancel. The animation should be at least 10% (probably more) faster, and it would be really nice if the sound didn't play before the projectile was launched. I believe this alone would make Quinn's ADC experience more in line with all the other ADCs, which I think is your goal with the proposed changes.
