This late in the game, 1 point into protector spirit for bloodlust should be better than Berserrker.

Have you considered using Fawkes+Xis barb helm?
The helm alone adds 240% spell damage at lvl 120. Barb skills would improve everything a little bit, including bloodlust buff. The +150 energy would allow for more points into dexterity without sacrificing damage and the laek might lessen dependency on eagle stance. If you have auhe,
Nero
would save 19 pts in fortress, you'd lose some rainbow damage but I think Path of Flames with all the fsd and pierce would make up for it, elemental proc on helm would be improved for the same reason.
I like the build though, its nice to see the lesser known items getting used in interesting ways. +1
