Your build looks good, I like the slottign you have on siphon life especially. As far as reccomendations, the only things I saw that I would change is that I would swap performance shifter in to dark consumption and touch of death in to smite. this will shift you to slightly better AoE defense while maintaining over cap melee defense. It also helps to mitigate some of the endurance problems you will face (although you will also need to farm both endurance granting accolades).
From the slight bit that I have learned over the last few hours, hope that helps 
Tyvm for the reply . I like the performace shifter in dark consumption idea, I did do it before soley for damage output and figuering there will be minions around but to fuel me but they do die rather quickly with soul drain and and dark consumtion in a drawn out fight. Not looking forward to farming for the end Accolades Ughhhhh....
The only problem with your Siphon Life is the no recharge at all in it.
If you remove the three res slots in True Grit and distribute them over your travel powers for the third Zephyr you will cover your AoE hole at the cost of 6% res to fire/cold/etc.
You had Phallanx Fighting set to 1 ally in range, btw.
Dark Consumption serves you better with endurance for the times you get stuck against one single enemy, IMO.
I shuffled your slots around to show what I mean. One of your purples from MG was put in SL, but you can put a Crushing Impact damage/recharge instead for minimal difference.

Ty for the advice , a few people questioned why i do not have any recharges in siphon life , the reason is because i feel i have enough recharge to run my chain SM,MG,SL, with my recharge bonuses so more recharge seem redundant to me. I love the suggestion of end mods in DC . I would go for that but 9 out of ten times im on a team and have an abundance of enemies around to fuel myself . I definatly will work slots around for more aoe i know its lacking and that will help alot , anymore suggestion and comments are wanted and ty all again!
