Ugh. I can use any help anyone wants to give. I'm about to throw in my multiboxing towel.

I need the moron's guide to ISBoxer WoW macros. I've watched MiRai's video on rotations a dozen times, but figuring out the right mix of steps, /cast, /castsequence seems beyond me. Any suggestions? (I've tried warrior, prot pally, and arcane mage with very little success)
