I had one of my alts running in Auchenai. We start the dungeon, and we were in it a minute before I realized the tank was not wearing any gear. Then about 3 minutes in, the tank asks everybody to take some gear off. Two other characters basically stripped down to very little gear. The healer and I ( a ret pally ) stayed in full gear.
We weren't dying at all, but we were taking forever to kill stuff. So, I asked why they decided to do this, as I had never seen anybody do this before, and I got an answer like "Dude, people have been doing this for a long time".
Well, I have played since about the 1st month of WoW, and have never seen anything like that in a dungeon. Sure, I have seen similar in cities, but never in a dungeon.
Is this common?
