Last night I was working on my warrior by running the low level roulette repeatedly and left the join in progress checked. When I got into one run where I was placed in a group in progress they said the previous tank had abandoned because he didn't feel like running Tam Tara and that it was common.

So my question is this really that common with low level dungeons?

To those who I may get teamed up with, I will not abandon you. I hope that I can continue to help others get their first clears of dungeons so they can enjoy this game as much as I do.
