So this seems to be happening a lot to me and finger on our priest and loc, I guess we are just lucky.

So we enter a random dungeon and end up in SFK with a warrior "Tank".  This "Tank" was a fury speced DPS warrior that would not pull and just sat in the back the whole time looking pretty.  15 minutes to kick .... I hate you blizz.

It is decided to have the rogue tank and I would just keep him up (got to love OP disc Priests) and we continue onto the first boss.  First boss goes down with no hitch and for whatever reason the first DPS decides to leave (think it was a hunter).  Time to requeue.  Finger DPS, Rogue DPS, Warrior tank/DPS, Joey DECLINE.  I tell the warrior that in his spec he is not a tank and needs to queue as a DPS and restart the dungeon queue.  Joey Heals, Finger DPS, Rogue DPS, warrior Tank/DPS.  So by this point me and the rogue were pretty PO at the tank.  10 minutes to kick .... I hate you blizz.

Get a new mage in the instance and just decide to continue with the rogue tank until we can kick the warrior.  Get up to second boss with no hitch.  Right beforewe pull the warrior decides to drop.  Halleluja, No way could we POSSIBLY get a tank worse than that .... I was wrong.  Rather than wait for the tank we decided to go ahead and pull the boss with our rogue tank.  About 2/3 of the way through the fight we get our tank a feral speced druid, in bear form, with about 700 health (party average was about 1400-1500).  Druid pulls just one of the adds on the boss.  I procede to continue healing the rogue and by this point am getting low on mana so the druid is left to his own.  The druid dies then the boss dies.  Then comes our favorite line from a tank "WTF healer dont you know how to heal" (Langauge may have been cleaned up a hair for childrens sakes).  At which point it is decided that the druid gets no heals until the boss fight and dies multiple times on trash.  Can not kick another player from this instance ... I hate you blizz (even though no one had been kicked).

Third boss, you know the one with the big desecration that takes up about half the room.  You know BIG AND GREEN AND OBVIOUSLY BAD.  Druid pulls and decides to stand in the desecration using up much of my mana to keep him and the rogue alive standing in the bad crap.  By the end of the fight I am completly OOM and out of drinks.  I tell the group "BRB need to buy some mana drinks" and teleport out of the instance to Ironforge.  While walking to the innkeeper to buy drinks the druid decides to pull and succesfully dies.  While purchasing at the innkeeper the mage decides to pull and succesfully dies.  While teleporting into dungeon the mage and rogue both leave the party leaving me finger and the druid "tank".  I get up to where the druid had pulled (still in his body btw about 5 minutes later) with the druid demanding a rez.  I procede to teabag him and have finger pull out her voidwalker to continue down the instance.  Can not kick another player from this instance ... I hate you blizz.

This is where the instance started to run smothly.  Voidwalker as tank, loc as DPS, and priest as heals and oh yeah Druid still in body asking for a rez (Eventually he "DC" probobly pulled the plug out of frustration and threw the computer out the window crying to his mommy about how mean the people in the videogame were to him and proceded to get slapped by his mother for destroying thier computer, at least I hope).  We succesfully 2 manned the instance down to the last boss which was too much with all the adds he summons.  So we ninja invite bree to complete the instance.  Tanks are nice that can 2 shot the bosses in healing spec.

So in summary ... FAIL TANK, FAIL TANK, FAIL TANK, YAY FINGER, YAY BREE
