I'm currently boxing a prot pally and holy priest duo with great success.

Now I'm already planning ahead to my next dual-boxing project once I get them to max level. I'd like to try dual-boxing two dps classes together, but because I don't in the end want more than one of each class @80, what different-class dps combinations work good to dual-box?

There's obviously some complications, like doing warrior/rogue they gotta do different moves but ideally on the same keypress each one does a different dps move (don't worry I won't try a backstab rogue or anything with positional requirements lol).

Some dps classes I already have going, so I could team them up with an alt but I'd have to first level the alt to catch up...I'd prefer to have the team start together at level one.

With that said, my dps classes I don't currently have going on the realm I play on are:
1. Warlock
2. Rogue
3. Warrior
4. Shaman

And the ones I do have that would have to wait for their partner to catch up in levels:
1. Druid (balance) L18
2. Mage L13


I'm hearing alot of love for the balance druid / elemental shaman combo...that's one I could do if I first level the shammy to 18 so he/she can start at the same point as the druid.

EDIT: Since I'd have to worry about leveling to shammy to roughly the same point *AND* have the same quests completed and ready as the druid, and the druid is only L18, mightn't it be better / more worthwhile to just delete the druid and start him over given he's only 18?
