When I first tried to get Keyclone working I ran into this same issue. I tried for hours to get key broadcasting to work, and it never did. Once Octopus added Maximizer functionality I switched and have been happily using that. I would highly recommend getting Macaroon for a Barmod - Then create a single, hidden, button that is in the middle top of your screen. Every key you want that toon to ignore can then be bound to that single button - the best part is that when you want to rebind the key you can simply do so within WoW, so you can essentially reconfigure on the fly.

As for your setup, before you get too far in I would recommend 3 warlocks instead of 3 mages. I have Pally/2xMage/Warlock/Priest - and the Warlock provides more damage, more utility, and better CC than the mages (for a multiboxer).

  • Sheep is nice, but at high level Prayer of Mending makes a pet as an off-tank great for CC - and that will work even in heroics
  • Banish is wonderful for CC
  • Water/Food is nice, but unless you are deep in an instance it isn't necessary.
  • Soulstones can get you through "multibox issues" (some toon manages to aggro something you didn't wanna aggro and you wiped).

Personally if I could do it over again, I would have 2xWarlock, 1xMage - so I would get the benefits of the portals/food with the benefit of 2 pets and 2 soulstones (one for priest and one for tank, or 1 every 15 minutes if needed... though I haven't really run into that).

In fact, I am in the process of leveling a lock on one of the accounts for my mages for that exact reason
