Can someone explain monks from a multiboxers perspective?

Thanks of the info guys, but in my head it only nerfs you to play as 4 monks, why?
-There can only be 1x EP on a single monster, and therefor the 3x other EP's applied is wasted, even with the Impending Doom rune since it triggers on monster death and explodes around the mob itself with a 1 x 6350% dmg as wpn dmg.

I'm not sure where you get there can be only 1x EP on a mob. Each monk can have 1x EP on a mob. So 4x EP on a mob with 4x monks.

A single monk can't stack more than 1x EP of their own, on a single mob.
