Valid statement, but like I said in my first post: His friends and advisers warned him. He had every chance in the world to make the right decision, and his pride for Grom blinded him. Even AFTER Garrosh was Warchief and Vol'jin contacts him half-way through Cataclysm and updated Thrall on Garrosh's evil behavior, he made no effort to correct his mistake. But now, all of the sudden, now that the world is falling apart again, Thrall takes interest. Correction, Vol'jin is the one who is leading the charge here, and his life is on the line because Thrall made a grave mistake and failed to correct it (or even attempt to).
