Ok, WC cleared at 20, could have done it at 19 I'm sure, but due to not having time to finish it I ended up doing it at 20.

Sadly I messed up the final escort quest as I hadn't cleared before accepting it, and the Tauren died - So I will have to come back and redo that at some point, but I think I need a fresh instance in between.

The 'grins' are 21 now though, time for totem quest and then SFK before going back and finishing last quest in WC (If I can be bothered :P)
