Healer spec and have Mark of Shifting.  Stag form at the entrance to the under belly. Go to the underbelly. Switch to tank spec. The limitations:

1. Once you change shapeshift forms you lose it. (cant fly or hearth or do anything). You can fly from the flight master with this.
2. Once you zone to an instance you lose it. (no mythics or regulars or anything).

The feasibility of this is awesome for soloing. I pulled HUGE packs with Ysera's Gift plus this. it adds quite a bit of healing. But dungeons are out of the question.
