Today on Birdfall, I had a mediocre group in Throne of the Tides that lost 3 healers. The first healer left after three wipes on the same boss. The second helped us through that boss but chewed us out for being terribad and left. The third stayed until the last boss when the tank had to leave and the group fell apart.
Personally, I would have liked to give props to my group even if we were pretty mediocre. The tank and other dps were new to the instance and perfectly willing to admit when they didn't know what they were doing. But they were also willing to keep trying. They kept a quiet, honest respectability around them that the second healer didn't possess in his littlest finger. He might have been "pro," but his social skills were terribad and got a /ignore from me.
There's something to be said for a group that rolls with its faults and doesn't implode. I might not have rated us very high in skill for that run, but I would have given my group mad rep bumps for tenacity and patience.
I think I'd like to leave a group or finish a dungeon and get a popup for "Did you enjoy this group? Yes/No" and yes gives a rep bump to everyone and you can also choose to rate each player individually:
Skill: Terribad -- Poor -- Mediocre -- Fair -- Good -- Outstanding -- Don't Know
Attitude: Terribad -- Poor -- Mediocre -- Fair -- Good -- Outstanding -- Don't Know
