Activated Xtnd I also saw Elemental Shamans staying in the back and trying to heal. I think people like that are very confused, they are trying to do everything and end up doing nothing. That's where a Shaman PvP guide can come in handy, it will tell you what you need to do with the spec you choose. If you can't find your spec in such a guide it's probably because you trained wrong.
