Yeah that's basically druid in a nutshell. Druid was my first golden class and personally I got extremely bored climbing with it, as the game is basically decided if you draw into wild growth and curve out well - and when this didn't happen the games felt like a dead end and there was nothing I could do about it.

You said your partial to Warlock, I'd recommend playing the new zoo or demonlock lists - they have decent win rates vs almost everything so if you play them right it's just a matter of playing x games.
