Watch some videos by Muselk. He has more than deserved the few plays of the games he's gotten as Zennyatta (I butchered that, I think). Heck, Mr Muselk is still getting them every now and again. If he isn't persuading entire teams to play one character

A few minutes ago i actualy witnessed a Zeyatta getting the play of the game for managing to land a killing blow on pretty much the entire enemy team in a few seconds. Which allowed my team to take the last point and win the game. It was pretty amazing to witness.
