I'm still not too sure about the viability of ele shamans in 4.2 in pvp, definitely not when boxing. Blizzard tried to make up their weak defence by giving them a few new offensive abilities. That doesn't change the fact that we still die in a couple of globals. One rogue can easily kill 1 shamy on his own. That and the retarded lockout periods of your nature spells. Ghostwolf, thunderstorm, heals, ... are all nature based spells.
