It's almost impossible to not have to work in WoW. First the game is created to really open up at top level. Once you hit that top level it's impossible to keep progressing (ie. gear) by yourself, because the endgame is purely multiplayer. You NEED many other players to really do anything, besides getting rich. You can't join a guild because all the ones that are worthwhile are a bunch of elitist assholes. So you have to be as good as them to even get in. So where do you start!?... Don't even get me started on rolling a DPS toon either! If you can't tank or heal you're basically worthless..
Of course I'm generalizing, but I'm pretty sure all new players face this. It's very frustrating.
