I've been trying this new build and its kicking ass. It's basicly Quin's Generator Build with Inna's set pieces instead of Cindercoat, Magefists, Depth Diggers and Leoric's Crown. Swap out Unity for RoRG and Ancient Parthan Defenders for Crudest Boots in your cube.
-Much more damage.
-Loads of Mystic Allies that distract mobs.
-Looks hella cool with all four mantras and an army of mystic allies.
-Take more damage. (no Unity)
-Less CDR. (no Leoric's crown)
I'd say try it out for yourself! It's awesome.
If anyone has any suggestions as to what to change feel free to share em!
Tried swapping Focus + Restraint out for CoE + unity but it resulted in way less damage and therefore too slow once you hit 70+.
I am running into problems with getting instagibbed by the Reaper of Souls mobs and the harder Rift Guardians when Epiphany and Forbidden Palace is not up. If I was able to swap out something for 50% damage reduction that would help. But I can't find anything that woulden't severely cripple the build.
