Same problem I'm having.

Been there 7 times in the last two days. I'm always the OT, the problem isn't that new people can't learn it (and every group has multiple new people in it) the problem is that after the second wipe, someone insults the tanks and leaves. Then we wait 20 minutes for a replacement and have nothing. Then everyone else ends up leaving.

The problem is people who are so impatient they can't wipe more than three times without crying that its too hard. They don't even stick around long enough for the echo to make much of a difference.
