I got Multibox all setup and running in about 30 seconds (kudos to Micah) and fiddled around with my two mages. Things seem to work well for the most part and i'm guessing it will take me a while to get used to it but there is one thing I could certainly use some help with.

First my setup:

For the mage on the 2nd box, I removed all movement key bindings and made macro's for all the offensive spells with minor variations of the following:

/cast [target=focustarget] Frostbolt
/follow <Name>

When I log in the 2nd mage I set the focus to my first mage and in the follow command I use the name of my 1st mage because I haven't yet figured out how to make /follow work any other way.

I have Multibox setup to only broadcast keys (not mouse). The 2nd mage follows me around just fine, and will cast fine as long as i'm moving forward. The problem arises when I have to Frostnova a target and then back a few feet away, turn around, and start casting. When I do this, the 2nd mage ends up in front and facing me when I turn around on my 1st mage to start casting. Becuase he's facing me, he obviously can't be casting at the target behind him and I get the expected "Target must be in front you" message.

So i'm wondering how others have gotten around this. The only thing i've been able to do so far is on my first mage when I turn to run around, I get to the point where I want to stop and do a 180 degree turn, then walk forward toward the target a few steps. This causes the 2nd mage to then go behind me and also do the 180 turn. This is far from ideal because by the time I get done with all the movement and positioning, the frostnova has roughly 1 second before it breaks.

To give you some context, i've been taking both mages (lvl 65 and lvl 60) into Blood Furnace to farm XP, gold, rep, etc. With two sheeps most of the fights are trivial but Frostnovas are used quite a bit. The tactic being pew pew, Frostnova, get some distance, turn around and pew pew some more.

I hope my explanation makes sense and some of the experienced multi-boxers can give me a few pointers on how to improve my setup / macros. I'm also questioning weather the /follow attached to the end of each spell macro is needed and if I should instead have a single key bound that I can spam the follow when I need it. Thoughts?
