My Shaman team hit 20 tonight (after clearing WC at 18).
Now I've got my Ghost Wolf (was dying to try that out), I'll be re-writing all my macros and enabling PiP as per the instructions.
I'm hopeful this will greatly increase my flexability as WC showed me I cannot continue having my main as such a single point of failure (though he collected nearly the whole of the "of the Fang" set today...lol).
