They added heirloom levelling in fishing and it can at least be done when watching tv or doing something else online, and cooking has power levelling but what about archaeology? I think it's a feature that belongs where pet battles are.
We all know pet battles would not be account bound if they were released before MoP so archaeology not being account bound seems very disconnected. It's one of those "side games" areas of the game that really doesn't belong in re-levelling on new mains.
