Hi. I've been running with a tankish Monk friend of mine through the early parts of Hell. I came up with this build towards the end of nightmare and would like to know if it would be viable in the later acts of Hell and going into Inferno. This is all AoE and switch to another build for bosses.

Basically what I do is place a Caltrop on top of my monk friend as he pulls as many mobs into him. Run back a bit put Mark of death ontop of the group and spam Multi. Once I run out of hate I pop preparation and with the Suppression on Multi I regen my Discipline pretty quickly have enough to pop Prep the next time I run out of Hate.

Let me know what you guys think!
