Found this on reddit and had to share. I tried it on my warrior and with the constant Might stacking (I could keep it at 10-15 stacks easily on boss fights) from FGJ, Signet of rage, and active weapon swapping, I was able to consistently do hundred blades of 25K, 12K whirlwinds, and 13K Eviscerates. Considering only one of my accessories is zerker, and I was not swapping weapons that efficiently, you can see the damage potential of this build is impressive.

I kinda skipped the gear section as that is really up to the individual. I go with runes of strength, Sigil of Bloodlust on my GS, and Sigils of Force and battle on my axe and mace. You definitely want to go with empower allies on dungeon runs, as the 150 power for everyone in the party is HUGE.
