Omg, why are 60s and 70s setting up on Ragnaros again? I've got a toon all planned out for 70 on Deathwing.
As for other brackets, you're going to need to give more time. Most of us are busy rebuilding all our stuff. For example, not only am I leveling toons to 19, 29, 39, and 49, but I'm also farming to rebuild my supply of enchanting mats. It's a non-trivial task to farm up enough mats for multiple mongoose, soulfrost, and spellsurge enchants, along with all the standard ones.
If you're bored, I suggest building another twink in another bracket, or figuring out where you can gank people, or making friends, or better yet recruiting some more friends to play with. Molten's twinking community has only been awesome when multiple people work to bring more players into the fold.
