Well after about 2 years of playing WoW I never really delved into Macros, but when you understand what teh basic comands are it's pretty straight forward, so i managed to write a simple;

/target TOON

/assist TOON

/cast ..............

Works for now.

The screen thing, i'm using a wierd configuration right now so the display setting doesn't show, but i'll play around.

Next; I'm using two warlocks. Just got their pets, but is there a macro to make the pets on both characters attack who is being targetted right away? Or do they only attack when their master is under attack?
