Help with Running a Warrior/Mage Combo

I am new to multiboxing and decided to start small with just two accounts. I am leveling a warrior/mage combo and have gotten them to 20 in 2 days real time. My current setup is fury/fire with the warrior being the main. when the warrior uses heroic strike my mage cast's fireball, cleave is fireblast, demoralizing shout is arcane missles. Is there something that I can do to improve this setup any? It seems to be working ok, but I have to spam heroic strike to get the mage to cast fireball alot.
