They must have had their B-Squad in.
My guild's raid leader was there on his DK tank as well.
We got through the Arachnid Quarter just fine as any mostly retarded group can do. DPS seemed a bit low besided a Rogue who was killin it. Then the fail started to creep in during Plague Quarter. First, we were getting a few people that were getting killed by the slimes because they would not move. These are ranged DPS mind you. Not melee.
Then on one of the gargoyle pulls DPS had their head up their ass and didnt kill a single one of them somehow. 28 stacks of the debuff later, we had us a wipe. They could not follow a simple instruction like "kill the skull". This guild is deep into Ulduar.....and cant focus fire on a target in NAXX!!!
Then we get to Noth. It goes fine despite dps seeming to be a bit on the low side. After we down him, we notice that the hunter is not there. HE HAS BEEN AFK IN SW FOR THE LAST 15 MINUTES!!!!! And of course they allowed him to continue in the run. He of the 15 minute afk and dps below BOTH tanks.
We clear all the way to Heigan, and then there is another afk....followed by another afk...followed by my playing 80s tunes in vent....followed by an announced 20 minute afk before a boss!!! WHO DOES THAT?
At that point, the raid leader from my guild and I were at the end of our fail ropes. I told them I dont have time for this shit and hearthed. The hunter who had AFKed thru the Noth fight told me to learn to be patient....to which I replied "LEARN TO DPS HIGHER THAN THE TANKS".
AFKs will kill the flow of any raid. In a pug, it is just going to piss people off and cause them to leave. I dont need much of anything out of Naxx and was spending my time to help. If you are going to be AFK 40 percent of the time, you are going to ruin the raid, or get booted.
On a side note, my raid leader (DK tank in epics with some blues still) was third on the damage meter. The rogue was in first by more than double any of the other dps. I did 40 percent of the healing....with three healers.
If you are going to run a raid, get your shit together. I dont want to sit through 50 afks and not even finish two wings in two hours. Unacceptable.
