There’s a Druid feedback thread in the PTR forums.
You and that person may have a lot to talk about. I can’t say anything about Druid as I don’t play then myself. All I know is, there is a broken build on the PTR where they do negative damage and one shot things. Cataclysm build of some sort. I don’t know all the details, but I imagine it’ll be fixed before it goes live.
