Thought it could be cool if shamans could be tanks. Could harness the power of the earth to protect the shaman. Like a "Earthen Form" a persistent form where we call the earthen elements to cover the body in stone. Somewhat like the bear form for druids. Keep the maelstrom aspect where rockbiter or boulderfist is the generator for maelstrom and aggro. Spend it on stacks of more "stone armor" like how warriors use rage for ignore pain. The list could go on and on. What are your thoughts?
