This my build, though its not that common, I feel very comfort at mp10.
My English is not good enough, I try to explain a little.
Shock Collar: hatred generator, disp generator (night stalker), 160 High proc rate helps to keep the mods fars away by kb.
Echo Spike: main damage output against large group of monster.
Rapid Fire: for single monster, it kill really fast. I m looking for the upcoming burf on 1.08 patch.
Punishment: Restore hatred, my point of view: hatred = damage output.
Gloom: defensive skill, no explain. (sometimes I replace it with Caltrops- bait the Trap, it greatly improve my dps, however without gloom, its really hard to against elite with dmg reflect affix)
Smoke Screen: defensive skill, no explain.
Archery: no explaination.
Steady Aim: good skills with windforce.
Night Stalker: disp is the most important part of this build.
Conclusion: use Shock Collar to keep distance with enemies and restore disp and hatred. Generate Hatred from Punishment. Use Hated spender to create main dmg output. The build needs lots of discipline consumption, large disp amount (ie nat set) and Night Stalker is a must.
Something minor: I got Chance to fear, freeze and immobilized on my helm, belt and boots, those are bonus to keep the monsters far away due to the high proc rate of Shock Collar.
I always looking for a DH only mp10 run, if any1 interest, please add me as friend in game.
