Here's where the elemental shaman finds a real dilemma
WOW Gold. The Protective Barricade of the Light is a mere ilevel 200, and ideally, you want to grab something better
Buy WOW Gold. There's one other shield you can grab pre-raid, and that's the Protector of Frigid Souls out of normal Pit of Saron
WOW Power Leveling. The good news is that it's a noticable upgrade over any other shield you can find outside of a raid. The bad news is that it comes loaded with MP5. Oh,
Buy Aion Gold and the fact that the only people who seem to run normal Pit of Saron these days are paladins and shaman looking for that very same shield kinda messes with your odds a bit
Aion Leveling. When it comes down to it, unless you're going to be off-spec resto, there's no reason for an elemental shaman to waste the time.
