I have looked through the skills, There is nothing new that would help a invinca monk. The two new smiteing elites are specially designed not to be useful for 55hp farming. One even takes the liberty to deactivate all your skills. Also there wouls be no point in useing Spell Sheild over Sb as Tsunami Rain says. While sheild spell will not be good for 55hp monks I'm sure all you orison spammers wil east it up.
Although the new Earth Ele elite is going to help out 55hp E/Mos alot. Shockwave is amazing.
Basically, don't count on many of the new monk skills helping 55hp farming.
Although I'm think The new protection elite called life shealth is going to be very interesting. I bet if you could use it with a 55 monk buuild and not need any breeze or mending. Although you would still need mending and breeze to vounter health degen. So I net a 55 build with life shealth would be very interesting! It will at least help tanking 55hp monks(not nessasarly for UW)
Rage signet doesn't sound like it will help much because 1. signets take a while to be casted 2. Not asll creatures use adrenaline 3. Its not aoe, so it will only damage 1 creature(which will make farming slow.
All the monk smiteing skills have a large recast time to so its not really like you can squeeze a few smiteing skills into a monk build and use them all to kill a group on enemies(at least not very fast).
So I personally don't think much will come out of the new monks skills for 55hp farming. Maybe skills in other professions though.
