I'd honestly rather they don't change her if it's not for the better.
I'm getting so used to playing her now that if they change her drastically (removing her ult damage) I might not want to play her at all... It's a very fine balance.
I've played hundreds of games with Quinn now... she's pretty much all I play. I really wish they would just fix her issues instead of doing these weird stat swaps. Fix her AA so it's not so clunky... Give her better base stats or something... She's hurting pretty bad. I mean BRAUM literally beats her in every base stat... including AD. SERIOUSLY. I almost choked when I saw that Braum out-stats Quinn in every way, short of range.
edit: I realize Braum is meant for support and he has huge cooldowns, etc... But that's besides the point..... Quinn still has some of the worst base stats for an AD.
