Need help on OF tank build for doa(ele/x)

I looked on wiki and it only has warrior obsidian flesh tanks. I just got my elementalist there and was hoping I can be able to tank for them. Or I guess go SF nuker build but I think the tank part would be easier.

Can anyone help me with a build for either of the two? I am hoping more for an obsidian flesh build but I will take whatever can get me into any group.

i've run this build for Gloom once..works very well but u need A LOT of practice, prevent interrupts, timing OF, etc..
E/R
16 earth - 12+3+1
11 wilderness survival
rest into energy storage
[skill]Armor Of Earth[/skill]
[skill]Stoneflesh Aura[/skill]
[skill]Kinetic Armor[/skill]
[skill]Obsidian Flesh[/skill]
[skill]Serpent's Quickness[/skill]
[skill]Glyph Of Concentration[/skill]
[skill]Aura Of Restoration[/skill]
and last slot optional - earth attunement, rez, etc..

and u need balthazar spirit from the monks to keep ur energy up. This thing can pretty much tank anything and everything

its easier if u run SF though, and i mean WAAAAAAY easier, heres my SF build
E/X
[skill]Searing Flames[/skill]
[skill]Liquid Flame[/skill]
[skill]Glowing Gaze[/skill]
[skill]Fire Attunement[/skill]
[skill]Meteor Shower[/skill]
last 3 is optional - arcane echo, rez, glyph of lesser energy, mark of rodgorts, lightbringers gaze, etc...

elementalist is by far better than warrior, and the build alpha put up there is pretty good. but you should take out the extra kinetick armor (he probably ment armor of earth) and addd in stone striker and storm chaser. just make sure you use skills like this:
serpent's->OF-whatever else->OF(just before OF and SQ end)->cancel out SQ with storm chaser->SQ(right before OF recharges)->and then start over at step 2

Where could I use the earth build? I also got a tip of using ward of stability for the last slot in the OF tank build. Also how much is needed with a 20% enchant mod for wilderness survival inorder to keep it up permanently? Would say 9 be ok?

Could it be used in places besides gloom?

@ mercenary - i think at 9 WS u would have about 5 second gap between the OF and SQ, 20% is a must also.
@coloneh - i dont see the point of canceling out SQ..? and storm chaser is uncessary if u have balthz spirit from a monk

So, then I am going to absolutely need +11 in WS to keep it up permanently?
