I have a couple of full group teams at lvl 71 and lvl 75, plus my 80 team.

With my druid team I can queue because one can be a tank, one a healer, 3 dps.

Once I'm in I can then kick the tank and invite my 80 prot pally. This also works with my new lvl 27ish group. I'm wary to do it though as I don't want the levels to be different. At level 21 and 22 with the new team I couldn't get in - had to grind out a bit more xp and get them all to 22. Silly really.

On the new group I'm less than impressed with the randomness as well. I played last night for many hours constantly hitting it when the debuff ran out and all I got for 3 full levels was Gnomer.... again and again and again. I did the one RFC that came up just to reward the server for picking anything but Gnomer.

The only nice thing is the random bag loot. After about 3 random runs I've got best in spot gear for all 5 guys.
