I was trying to do Mana Tombs yesterday. I finally got a halfway decent group consisting of a hunter, a priest, a druid, and a paladin (me). The group leader goes to look for a fifth. This is what I see in General chat:
[Group Leader]: LF1M Healer
Apparently, I was Protection, the priest was Shadow, and the druid Feral. And 3 of us wasn't good enough for the leader. Honestly, that's just crazy.
