I have been trying to tweek my enhance shamans dps.. he has about 469 gear score..two agil axes you get from Klaxi at exalted. I have seen similarly geared enhance shaman doing around 50k sustained.. i cant keep him at 25k.. SO i will keep at it.. not sure what i am doing wrong with him. But both enhance and DKs top charts in LFR all the time ( i don't do normal raids so cant compare those )
