I tested that thing on during the Orozar quest several time sucessfully, even with some pretty sucky monks.
Melandrus Resilience is the thing that keeps me alive when the they start stacking all the conditions and hexes on me. It can't be stripped off by enchant removal and doesn't really interfere with any spells the monks could use on me. It stacks with stuff like breeze and shield of regeneration. The energy regeneration it provides isn't too bad either.
I mainly consider endure pain to counter the end of Melandru's Resilience, since that's when my health bar starts decreasing fast

Hex Removal won't help unless all party members bring one. Even if one of monks would bring Convert Hexes it won't do much since the hexes and conditions are inflicted again in seconds.
You're probably right about fear me, but I didn't really see any skill that would give me massive benefits. To the limit is mainly used to feed "Watch Yourself!". Blocking skills are not really needed since the physical damage you take is nothing to worry about with watch yourself and Dolyak Signet.
What other damage reducing skills do you suggest ?
About the res sig : I dunno about you but in many PUGs I join things go terribly wrong sometimes (monks that rush in front to use channeling for energy management, necros with touch skills,...

)
