Following on from spots monk thread, and given there are 50 bajillion demon hunters.
Heres the build I'm currently using for Hell Mode: http://us.battle.net/d3/en/calculator/d ... XeT!cbZYZY
Essentially its hide in stealth, as most scarier monsters 1 shot you even with 25k hitpoints.
Mainly works due to my base 30% crit rate (10% from archery as I stick to hand xbows for the especially).
High crits obviously mean that teeth is occuring a lot for grouped up trash mobs, and when multishot is fired you have a good chance of critting 4+ mobs which then triggers Night stalker for a change of massive discpline regain.
Bat/Prep/Marked for death for added hate/disciple gain to fuel multishot and smoke screen.
Seems to working really well, I can easily solo some of the harder combinations of Rare hell mobs now.
Also, Smoke screen is the bees knees, breaks fear/stun/slow/frozen/avoid most aoe splash/avoids most attacks that are on route to you.
