Can someone explain monks from a multiboxers perspective?

Hey guys, I know some of you are good monk players, but in my head I cannot see the advantage of having 4x monks, I'll tell you why:

-Exploding palm do not stack, therefor 1 <=> 4 monks
-Since all of your characters are attacking the same target, your EPs wont spread quicket 1 <=> 4 monks

Things might have changed, and I could be wrong - From what I understand, EP doesn't double stack for a SINGLE monk, but every monk can apply their own single stack.

In 4 player games, EP used to do 50% health damage on explode. But in 2, 3, 4 player games, it was 30%, 20%, 10% respectively (silent mechanic). So 4x Monks - EP would each explode for 10% of the health in a 4 player game.
