I take normal Flurry build and make some changes.
T6 with this is very,very fast. You can try it and I promise you will love it :).
Flurry spam SWK clones and final explosion of Flurry is one-shot killer for Elites! You need only about 7-12 stack of Flurry to one shot elites everytime (depending on your gear stats)
Epiphany with Inner fire rune simply clear whole screen of trash when you run with Flurry . Amazing show of Epiphany clones :).
Have a nice farming
