As someone who mains as Cait and other ranged AD carries (Namely Trist), I'd say that she's pretty balanced as she is atm.
She's pretty slow, although her escapes might prove irksome. Her net and traps provide a very nice way to escape, but with decently high cds on both so at lower levels ganks can prove very troublesome for her.
She's pretty decent in team fights (Although I realize a lot of people here would disagree with me). Her trap can **** so much up in so many different ways and her Q acts as a really good poke to take out a decent amount of health. However, despite this she does get focused down a lot and her ulti is extremely unreliable when there's more than two people in an area at once.
Definitely not OP though.
