Keep Caltrops down to maximize damage while laying down AOE or focus fire.
Custom Engineering for increased trap time, Archery and Cull the Weak as obvious choices.
Hungering arrow and Evasive Fire to generate hatred.
Multi-shot for AOESpider companion and frost arrow to augment slowing if I run out of discipline, though I don't foresee this happening until the later difficulties
I think cull the weak seems like a pretty cookie cutter choice for Inferno, after all, if it can't catch you it can't hit you so with that in mind I made this build and want to know what you guys think and if/where it needs some adjustments.
I would like to squeeze Mark for Death in there but I'm not sure where.
