want something extremely simple?
3 mages
macros:
[1] /follow "main character name here"
[2] /assist "main character name here"
[3] fireball

there are your buttons for 1,2,&3 just unbind WASD for your alts and move using those.. easy... although you can bump it up and make better macros and such but this will get you started for now in about 2 minutes inch:
