Well I dualboxed two mages up to 24, but they just weren't doing it for me. I can't decide which two classes (or single class) to dual box. I suppose at 80, my main focus will be PvP, but that's a long ways away. How well do two shaman do? I'm not looking for the perfect, flavor of the month, combination for dual boxing. I just want something that isn't too difficult to work with but is enjoyable to play.

Since my second toon is always running behind my main toon, is it difficult to manage two melee classes? I have a 32 enhancement shaman whom I absolutely love, and I wonder if it would be worthwhile to get a second shaman up to 32 so I can dual box them. I've read that in BGs at 80, 2xElemental shaman isn't enough boompower to make it worth it. In the same thread, it was noted that 2xResto shaman would be better. But what about 2xEnhancement shaman? Or for that matter, would 2xDruids be better/more fun/easier? If so, which spec? I have a ton of experience with a single feral druid, but I've never tried two. Would dual boomkins faceroll in PvP?

Again, I'm looking for something that is fairly manageable while leveling and would provide some entertainment in BGs if I ever make it to 80. I prefer to nuke down single targets rather than AoE.

Classes that don't particularly interest me or that I can't have two of: Warrior, Hunter, Death Knight, Paladin, Rogue, Mage

I guess that leaves any combination of Priest, Warlock, Shaman, and Druid.
