yeah ele shaman DPS is pretty bad at the moment at 80, IN RELATION TO OTHER CLASSES. Yes, for those of us who had mediocore gear its going to be pretty awesome when we hit 80, and it'll be enough to do instances and other stuff, but if you just play a single ele shaman in a group and someone posts damage meters it'll be embarrasing even as I'm leveling my pally/mage/3x shaman team, my mage generally does 50% more dmg than my shamans with a terrible spell rotation too (just /castrandom blast, barrage, missiles). For PVP I just don't know enough really, while there is a lot of upfront burst damage, other classes also have lots of upfront burst, and everyone has a ton of HP, so no clue how its going to play out in 5s.

The good thing is that there have been a couple of blue posts that say they know its bad, hopefully it gets fixed in the upcoming patch. I think simple things like upping the lb coefficient and reducing the cooldown on lava burst could help a lot.
