I've got a lot of teams, which will level for Transmutes.
I'm particularly fond of (ie, will level and play both of these):

1x Prot. Paladin.
3x Elem. Shaman.
1x Demo. Warlock.

5x Feral (Cat) Druids (PvP).
Which is also:
1x Feral (Bear) via Dual-Spec.
1x Resto, via Dual-Spec.
3x Boomkin, via Dual-Spec.
Unless the Druids are seriously weaker then expected, this will likely be my primary team.

Also have, and will definitely level to 85th:
1x Disc. Priest.
1x Frost Mage.
1x Boomkin Druid (dual-spec Feral, if I need a tank).
2x Elem. Shaman.
Possibly trade (back) one of the Shammies for the Warlock, if the earlier team needs a dedicated healer.



The other teams are primarily for Transmutes... they'll level to whatever the new minimum is, but likely not a whole lot further unless leveling is a lot easier or I get bored.

I could see the 4x Warlock and 1x Priest (Disc) on the horde side leveling up to 85th at some point, but they will not be the first three teams to do so.

All of the aforementioned toons have Epic/Cold flying, or in the case of the Hordies, have transfered and sold enough cut gems to buy Epic/Cold flying.
