I play a Warrior and a Bard.

First time in AK as a Warrior I died from Demon Wall because even though I've watched the video, experiencing it for the first time is so much different. When the bees came around I forgot about the Repel so I fell off - everyone left. That was fine with me because I could queue up and get another group almost instantly. Got through it fine the second time around with a Bard showing me how to position the last boss.

As a Bard, I joined an already existing dungeon where it was the Warrior's first time and the DPS had left leaving the healer and tank. I could empathize where he was coming from because that was me once. It took a minute to explain boss fights and we got through the dungeon easily.

I've run into people who are petrified at joining DF groups for new dungeons because there are so many people who literally would rather throw abuses, leave, and wait 30 minutes for a group to start again than to explain a fight in two minutes.
