Enhancement damage is pretty good. If you don't mind specing into Echo of the Elements(30% chance to proc for enh) it puts out a lot of burst with double Lightning bolts hitting for 3ks on dummies
Healing surge heals for 7ks non crit without the glyph of maelstrom
Only bad thing is since the PvPpower thing lack of crit from agi gems causes Flurry to fall off sometimes
