Healer of MM?

We only get 3 hero slots, and I need 2 slots for my synched earth ele's.
I would like to hear people's oppinions on what is more valuable, a WoHybrid monk or a MM?
A Minion wall will be a huge advantage in area's where MM's work, if done right they are even acceptable in area's where they don't.

Now I've throwing in a random MM hero now and then when I didn't have the echoing rumble build yet or didn't have 2 ele's yet and concluded that it is a good idea to run a hero specific MM build, as they do tend to mess up with my [skill=text]Order of Undeath[/skill] build, and aren't eager enough to become part of the minion wall with the [skill=text]Mystic Regeneration[/skill] build.

And while heals can be done by pretty much any1, protting is something you need done well.
I tried getting ridiculous with a protection MM and can safely say a BoTM spam and protection healing doesn't sync well, nor do animate casting times and getting Prot spirit on someone in time.

So which is the lesser of 2 evils? Missing the MM for that 70% of the game where they are great, or missing a good protting monk, plz tell me what u think.
