I am just trying to get my head round it, my 3 mages are now lvl 60 and i want to start to use FTL early so when i hit 80 im confident with it. I am just playing around atm slowing setting up all the spells.
Ive got problems from the start, I hit '2' on my main and my slaves say they have no target. I have placed the 'I' button with the macro on it on the bars, and fireball on the '2' key. when i hit '2' on a main it also hits the 'I'
but the slaves just hit '2' and they dont pick a target. help please. Here are my keymaps and macro.

ToonA
‘2’ ---> ‘Fireball.on.Blastonce.target’
‘Ctrl + Alt + i’ ---> ‘Fireball.on.Blasttwice.target’
‘Alt + Shift + i’---> ‘Fireball.on.Blastthrice.target’

ToonB
‘Ctrl + Shift + i’ ---> ‘Fireball.on.Blastonce.target’
‘2’ ---> ‘Fireball.on.Blasttwice.target’
‘Alt + Shift + i’---> ‘Fireball.on.Blastthrice.target’

ToonC
‘Ctrl + Shift + i’ ---> ‘Fireball.on.Blastonce.target’
‘Ctrl + Alt + i’ ---> ‘Fireball.on.Blasttwice.target’
‘2’---> ‘Fireball.on.Blastthrice.target’
