Get the fliers. Even if you get them one at a time, you can do herbing and mining on the epic and then hop on a non epic mount to do dailies with the rest of the group. Not sure if you like any of the new mounts, but all the new flying mounts in Northrend require epic riding skill. At least if one character has it and you happen upon a Time Lost Protodrake you'll be able to use it.
