your setup does seem very well balanced. added cc on your helm and wrist would be nice but i don't think it'll be worth what you'll end up paying.
instead i would suggest some changes to your build. having owe seems a bit of a waste since you only have one item with elemental resist. swap this out with combo strike and sss with either Deadly Reach (foresight) or WotHF (blazing fist). DR should boost your dps close around 200. WotHF will bring your dps to around 180 while increasing your IAS to better proc LoH.
if you're ubering, swap SSS with BoH and OWE with Near Death Experience.
my thanks to @violentine, yahhaur and terminus for your kind words.
skip to @terminus please.
