I don't understand the downvotes TBH.
I used to play top lane last season, and she was the absolute worst to lane against. Quinn top has been flaring up like a nasty sore every few months or so for years. She comes into the meta for a moment, then flies back out for a few more months.
Thankfully not many people are playing her at the moment, which is probably why you're getting downvoted. When you do come in contact with one though it hurts, it hurts a lot.
Riot should address her because she isn't a new problem. She is not like Teemo either.
In my mind she symbolizes the end game for this obsession with making marksmen our all powerful overlords. The good part of Quinn is that she doesn't scale smoothly without someone feeding her. However she's not weak early game, and her range and blind can really force you under tower. It's not fun.
If you must play a melee against her I would advise picking something like BS Irelia to deal with her.
