That does bring up a good point. "tank and healer" appears to be everyone priority.

If you've got a raid full of tanks and healers (normally not so many healers), then you've got no DPS. And generally when tanks offspec to DPS, they're DPS set is worse then they're tanking set (because of gear priority) so they're DPS suffers.

Hmmm, I'll have to ponder that one. We did to "raid roles" for awhile and sorta forced everyone to pick a raid role and stick with it, and your toon would get loot priority for your raid spec. This worked, but I hate pidgeon holeing people into roles they don't want to do.
