has been OP for a long time, I can tell you as a Quinn main, but people are now only seeing it. Personally I think Quinn could be put in line by nerfing the W (,which really gives insane trading power early with huge AS steroid and MS buff), as vault is a pretty balanced ability. The vault gives her no invulnerability, so any well timed grab, displacement, or point and click cc can stop it easily. I do feel like the slow is a little too much tho, and it is really good when hitting Q AA E AA. With electrocute + ignite + ult this is insane Zed level damage early,mid,and late, which shows a clear problem. Tbh I think Quinn could really do with some passive or ult changes to really bring her in line with how old Quinn played, a transformation that made you change play styles in bird form.
