Yeah the glitch with baron/dragon is that her max auto range is somehow not triggering the passive now... In order to trigger the passive to proc baron/dragon you have to get slightly closer than her max distance... you'll then notice that it procs pretty quickly after that.
I actually wish they'd change Vault to place Quinn slightly closer to her target when landing... Because as of now, if you Vault someone, they are obviously going to run away from you, and they have just enough move speed from the Vault slow to start moving away from you before you land. Meaning Quinn actually has to run forward a slight amount in order to actually auto that passive proc from Vault.
So either make the stun last slightly longer so Quinn can actually land and shoot the AA without having to chase the enemy, or just have Quinn land slightly closer. Either way, I don't want to have to move toward the enemy anymore once I've Vaulted just to land the AA after.
I would only accept Vault as a skill shot if Blind was a pass through ability... Quinn has it rough as is against ranged champs, because most of your trade potential comes from the blind, and you can't blind a champ unless you can get around creeps.
I think it might make Quinn too strong though. You could blind people a lot easier and then AA through creeps on top of that. Honestly I like her Q and E as is... it's mainly just the glitches that are annoying.
Quinn needs some serious love, Riot.
