Dervish Tanking

So, I was wondering if it was still possible to tank as a dervish, using some kind of obsidian flesh build (I looked on Wiki, but it seems it is outdated). I often see GLF TANK in party search, and I thought it would be nice to be able to fill this role. Thanx for any insight!

You kinda just answered the question within the question. Go D/E, use Obby Flesh for Spell Blocking and other Earth Magic for xtra armor. Put points also into Earth Prayers and bring Mystic Regen. The PvP skill "I am Unstoppable" would help for areas with knockdown as well.

That being said, I've only once seen a Derv who can tank appropriately.

Groups that look for a tank often mean melee that can do tanking tactics, not a worthless build that don't do anything. When you ping them your damage build...make it clear to them that tanks don't do anything, especially with Ebon Assassins, minions, and spirits.

Spec 6 in Conviction, run "I am unstoppable!"+ 14 scythe+Zealous Vow + Mystic sweep+ Eremite's attack + Save Yourselves!. If you need any more than that, you're usually overaggroing or you can just tell your monk to not suck so bad and slap prot spirit + SoA/Seed of life on you. I've seen Avatar of Balthazar + Eternal Aura stuff, but if you need to spec mysticism for something that only gives +40 armor you're wasting your time (you can spec 7+ Earth Magic for armor of earth and not waste your elite slot, provided there are no enchant strips).

Don't run Obsidian Flesh, it's garbage on a Dervish. Your max Obsidian Flesh (at 12 Eearth Magic) is 21 seconds with an enchanting mod, Glyph of swiftness reduces 25% =22.5 seconds recharge. You're better off on an Elementalist, which can pump Armor of Earth to +62 instead of +53 and run Stoneflesh aura and stone striker with Geomancer's and Mantra of Earth, which makes up for +25 armor on a Dervish anyway (60+20+9 vs 70+20).
i.e. Glyph of Swiftness, Obsidian Flesh, Stoneflesh Aura, Armor of Earth, Mantra of Earth, Stone Striker, Grasping Earth, Sliver armor.

As a monk /facepalm whenever I see a defy pain warrior or obsidian flesh dervish. If you want to tank run a Shadow form assassin. Then you can blame your crap damage on Shadow form's damage cap :p

EDIT:
Think about it from a team standpoint. Do you want 2 characters with save yourselves, giving +100 armor to everyone that are also pumping out damage and other useful things (shouts, conditions, what have you)? Or do you want a character that sits there and takes damage and does nothing else? Even only one character with Save Yourselves, all your monk needs to do is keep an eye on the person unprotted (i.e. the person using SY!).

The closest thing to tanking:
12+1+1=14 Scythe
6+1=7 Earth Prayers
11+1=12 wind prayers

1 Zealous Vow
2 Mystic Sweep
3 Eremite's Attack
4 Aura of Holy Might
5 Conviction
6 "I am unstoppable!" (unlike other boosts this stacks beyond +25) see http://wiki.guildwars.com/wiki/Effect_stacking
7 Armor of Sanctity
8 "Save Yourselves!"

A bad idea: Balth
8+1 Mysticism
12+1+1 Scythe
10 Protection Prayers (breakpoint for SoA)

1 Avatar of Balthazar (Waste of elite slot since 70+40+20=130 armor, an axe warrior with I am unstoppable has 120 base and 140 vs physical)
2 I am unstoppable!
3 Eremite's attack
4 Mystic Sweep
5 Balthazar's Spirit
6 Protective Spirit
7 Shield of Absorption
8 Eternal Aura

You don't want to run 130HP in a party. If you get stripped you're out of luck, it's more or less instagib. Mystic Regen isn't all that useful either when you have high HP.
