Thanks for the replies, but i think i haven't made myself clear.

I have no intention of levelling 1-70 ever again, i did it 8 times separately, and once as a 3box team and have had enough :-)
All i intend to do is to use the toons i have at 70-80, and build teams of 5.

The toons i have are:
1 x 80 Paladin - Soap
1 x 80 Druid - Ghør
1 x 72 Shaman - Ghur
2x 70 Shaman - Zubwan & Zubtres
1x 70 Rogue - Wazza
1 x 70 Mage - Frizza
1 x 70 Warrior - Shaiah
2 x 70 Priests - Cian & Cixi

All the 70s (apart from the 2 boxed shamies) are in Karazhan gear or better, the paly is in naxx25/ulduar10 holy gear or naxx10 ret gear and the druid in naxx10 gear.
A hunter or warlock would be nice as suggested, but i have none at a high level.

Thanks for your suggestions
