thanks for the help guys. so far so good. I took your advice and decided to go with a shaman healer, paladin, and 3 mages.
I just installed Jamba. I finally couldn't stand the headache of tracking quests on all 5 chars at once anymore lol.

i have some simple attack macros for the 3 mages, that activate whenever i melee attack with the paladin. Whenever my main (the paladin) attacks, the 3 mages target his target and cast fireball. I have heal macros set up for the shammy. A macro to heal each party member. havent bothered making macro for buffs yet, since its too easy to just mouse over and click the buff. Having dual monitors is real nice for multiboxing.

So yeah, real simple/retarded macros. Gonna go with this until i start dieing alot because im lazy like that.

Ive been having some issues with PiP maximizer switch. I have my 5 chars bound to the shift+f1, shift+f2, shift+f3, shift+f4, shift+f5. Sometimes these keys dont work at all it seems, other times, I can switch primary screen to some of my alts, but others dont work.. Sometimes when i switch screens, the WoW windows end up on top of each other. What can I do to avoid this?
