Agree with you, one of the reasonable posts, though in my opinion there is nothing wrong now, and she already got counters which are highly effective against her including new ones like Torb, who just screws her whole ult up. She was nerfed more than enough, and with Ashe coming out it will be even tougher for her.
The majority of forum users thinks she is balanced btw, as evident by the big Forum Poll which provides interesting data about how the community sees the balance in OW.
