You should run double tanks, and solo tank raids. Best way to make friends.

Run a double feral team. You can dual tank, dual heal, dual dps feral/boomy. It will give you great practice to start instancing at 15. Less spells, and easier fights.

You have all the options there as a feral team. If you were running more I would move toward shaman. But with two you could tank/heal yourself. Which feral's can tank current LFR content in pvp gear.
