I ran this build last night in FoW solo to see how long I could hold off a crowd. Aggroed a crowd of 6. Held them off for about 10 minutes before I got bored and died. This is however a PURE defensive build. The difference between this build and a normal 55 build is that if you lose an enchantment that you won't die in 10-15 seconds. You also cannot do damage as a nomal 55hp ele can do. But you can be stripped of either enchanments and be alive for another 30-45 seconds or so till you get that enchanment back up. You will have unlimited energy with Essence and Balthazar's which you will need if your the only tank cause you will have to spam your spells to get the healing boost from Aura of Restoration. This will keep you at full health with the +10 health regen from Mending and Healing Breeze.
Now theoretically if you go with a team you will have at least 1 other tank with you. That other tank will take some damage off of you so you can replace Aura of Restoration with Heal Other that you can spam every 10 seconds IF necessary, combine that with ward against mele and you should be able to let your monks concentrate on other party members instead of just the tanks. With another tank taking pressure off, you should also be able to drop Essence Bond and add Obsidian Flesh which will last for 22 seconds with a 20% mod. I use Galigords Staff cause it's cheap and has the 20% mod. Gonna try and run this tonight in a team. Let you know how it goes unless somebody can run it first in a team. Please post any constructive comments or suggestions.
