I wrote this in the wow oboards but it was ignored so I write it here in hopes that someone will respond and tell me what they think
Elemental Fury (either a totem, passive ability, or talent): Whenever a buff is dispelled or whenever a shaman's debuff on a target is removed, there is a 20% chance that the shaman will go into a rage for 15 seconds increasing casting, attack, and running speed by 10%, and becoming immune to any form of CC (like bestial wrath).
I think this will alleviate many troubles for shamans. First off, this would stop people from instantly dispelling shamanistic rage, because the consequence could be enormous. It also fixes the whole CC/anti-CC trouble shamans have in pvp.
