I'm still new to the multiboxing but since I started I have been testing how to work classes together. I only dualbox so beyond that I've got nothin. From what I've found the Rogue/Druid combo works great as stated prior to my post. I use keyclone as well and how I have it set up is on my slave account I keybound a key (f1 in my case) to strafe my slave toon to the right, this breaks his follow command. I attached /follow ______ to the end of the normal melee attack to work as a pickup button to rejoin follow. I stealth my rogue, strafe my druid to break the follow command, and begin ranged on the target while my rogue creeps towards it.

As far as a Mage/Rogue combo it would bring a great deal of DPS to the table but as stated before, lack of synergy. Meaning your mage is only really helping your mage and your rogue only helping himself as far as utility and buffs go. This does not mean it wouldn't work, though. As I said, that combo will generate a lot of DPS. You will, as I'm sure you've figured, have to be extra careful when multi-pulling as you gain no heals from either class to compensate for damage taken with multiple adds. But this can easily be avoided.

So I guess my advice is keybind a button you don't use for strafe to break the follow and create (or use another way I'm not yet aware of) a hotkey to put the Mage back on follow. This is also being said under the impression you run the Rogue as your main. I would think running the Mage but controlling the Rogues movements may be a bit difficult as your camera will be following the mage and not the rogue. However, I suppose you could do this by keybinding keys for your rogue off keys you do not use. Perhaps make f1 your rogues forward movement, f2 back, f3 strafe right, etc. It would take a great deal of concentration and practice but I'm sure with enough patience someone could get it to work efficiently. Best of luck to you and I hope that offers some help albiet recapping previous help, haha.
