My PvE Build:
http://www.aocfeats.com/feat/hox/12b...c2641bdb41bf44
Best single target dps build I can make from tons of testing (you need a badass weapon, though). Move the 3 points from debuff to stun if you need the stun. Remove points from Butcher and debuff to get down to Molten Flesh for fire damage fights like Brothers, Pagoda, and Keeper.
Some will disagree since I don't include the 100 magic damage, but I see a bigger increase in dps from Butcher (it raises base dps for all combos along with an increase in BtD DoT because of the weapon damage % boost, thanks to Boesche for this one).
