3x Monk/Me with this build:
[build prof=Monk/Mesmer Smiting=12+1+2 Divine=11+1 Insp=6][Signet of Judgment][Castigation Signet][Bane Signet][reversal of damage][smiters boon][power return][mantra of inscriptions][resurrection signet][/build]
+1 Healer Monk
+1 Protect Monk
+2 Optional
If running dual hero teams, have 4 of these and 2 Prot/Heal. Try it!
Its very very easy to use, and very durable! I have completed almost every single dungeon with this build with no problems 


so when playing with other people and you need a heal/prot hero, you'll have to rerune them back and forth
