Controlling multiple chars at once (SE/SI mules in Zakum, etc.)

For the people who have mastered some kind of control scheme to control multiple characters at once, in taxing situations like bossing where you have to focus on everyone's health, would you mind sharing how you do it? I basically want to be able to solo zak with an SE and SI mule but keep everyone alive and try to control the characters somewhat simultaneously (or at least as much control as possible).

I use a dualshock ps3 controller with key mapping, at this point I don't use any sort of advanced techniques that more experienced players may use. I can simply switch between active windows and things with alt+tab but I'm sure there are more efficient ways?

Would anyone mind sharing how they solo and keep their mules alive in tough bosses like zak/ht?

Thanks!

 

Just have auto hp and mp pots on the mules and cast the buff whenever you need it

 

They also put their ap into hp
