Guess I would like some guidance too. But it is most likely gear, glyph, gems and possibly talent issue. I am using pinotnoir's cast sequence except I don't use searing totem anymore due to constant break of my CCs (caused a few undesired wipes on VP heroic). Here is my shaman:

Right now my Mage and Warlock can both reach nearly 9.5k dps, 10~11k with BL. But my shaman usualy stays around 7k~8k tops. Here are the mage and warlock armory both using pinotnoir's cast sequence. Possibly I can pull out more than what I am doing...
