I recently found a build for E/Mo that is super efficient and can pretty much replace most monks and not worry about dying. If there is no mesmer, then this build is almost unkillable.
Armor of Earth
Basically, just spam healing breeze and Heal other and when your massive mana pool empty just use ethal renwal to gain it all back via la Divine Boon. If you're the target must likely, use armor of earth and knietic armor, and maintain knietic armor, must warrior do like 3 damage to me at that point and a chain lightning only do about 40 damage. Nothing a breeze can't handle. If life is low just use ethal renewal to gain it all back, with like 4-6 enchantment on you, you gain about 20 energy per boon and 100 hp. =D
