With this build, I'm actually tanking even elites, and of course when I lose focus, I'll die. But most of the time, I'm doing really find tanking.
Of course with higher attack speed you can do even better. This build works better for those with 1h Crossbow.
Basically I'll stand in 1 area, cast the caltrops to increase my Crit C. Mark an Elite (because my hatred regen is bad) and place the spike trap infront of me waiting for them to come. Once they arrived, cast gloom.
