Howdy Sydidex and welcome to the forums!

i'm not much of a hardware boxer... outside of using the network to coordinate remote keyclones... but i'm sure someone good to KVMs will chime in.

as for formations... they are basically just creative wow key bindings. pick a key you aren't using... and have each clone do something a bit different when you hit. having one strafe right while another moves left .. and your leader stands still.. will give you a triangle pretty quick.

as for controlling pets... i had rolled my imps attacks into my opening salvo macro (there is a bit of noodling with targeting... i use focus for targeting... but that's outside of your question). after you have the macros on the same action button... hitting that button will trigger all connected wows (and for my 5x warlock group... would send 10 bolts o' joy inbound to the target... oh, what a great sight )

i hope that sheds a bit of light on your questions. if not, please feel free to drop me a note

good luck,

Rob
