Warlock tanking...

This.

they can't tank any dungeons (unless ur a lvl 80 lock facerolling yourself through Deadmines)

If by "dungeon" you meant "raid", I almost agree with you. But you don't have to go back to Deadmines, lvl 80 heroics are definitely tankable.

locks are great for tanking quests... not group quests, just normal ones.

Even without a proper Demo spec for Meta, just the standard SL/FG type of levelling setup, it's easy for an 80 lock to solo (not just tank) icecrown group quests and pre-LK dungeons. With just the right spec (and good gear), we can solo non-heroic lowbie LK instances too (like UP). I imagine with a spec/glyph set up just for doing so, we could solo at least half of the LK non-heroic instances, and tank all of them and even a few heroics with a good healer.

Or Blizz can add a glyph so we can all be happy:

Glyph of Metamorphosis
Major Glyph
Classes: Warlock
Use: Makes the duration permanent and removes the cooldown of your Metamorphosis. All damage done by the warlock his or her pet generates threat for the warlock. The increased damage component is removed.

edit:
A build that would work with this: http://www.wowhead.com/?talent#IZ0Gf...gzVoVcbVbh:Ndj

Using: Shadowcleave, Searing Pain, Felguard (increased threat) or Voidwalker (damage absorb), challanging howl, Demon Armor, Soul link, etc..

No, just no.
We are a pure dps class, and there are a few niche times we can tank, but then again so can a mage or a hunter pet.
That does not give us any right to have that option improved and turning us into a hybrid.
We are fine, well used sparingly as a dps class, and yes we could see improvements there but that is what we do, roll a different class if you want a tank and leave locks to doing what they do best - blowing things up.

they'd probably be better then 75% of the death knight tanks i run into.

Warlocks have no business being anything other than a DPS class. If you want to make it so VW can tank better again, thats fine. Just dont dedicate a talent tree for something that isnt more than a laugh.

I made a second shaman to tank for fun (Its PvP enhance/Enhance tank) since I already have a resto/elemental shaman. I wanted a challenge and to do something different. However, I will never be insulted if someone in my party doesnt want to do a heroic or raid if thats the character I choose to play. If I really want to tank I use my warrior.
