Code for making your action bars "less" full:
Code:
#showtooltip
/cast [mod:shift] SPELLNAME; [mod:ctrl] SPELLNAME; [no mod] SPELLNAME
This will make the spell show the no modified version at all time, unless you press Control or Shift.
Example:
Code:
#showtooltip
/cast [mod:shift] Outbreak; [mod:ctrl] Army of the Dead; [no mod] Empowered Rune Weapon
Now, this will show the Empowered Rune Weapon at all times, unless you press Shift/Ctrl. If you press Ctrl, Army shows up at the place instead of the Rune Weapon. Same thing with Outbreak.
(You can add ALT as well, you just need to modify the code a bit)
You could even do:
Code:
#showtooltip
/cast [mod:shift] Strangulate; [mod:ctrl] Dancing Rune Weapon; [no mod] Mind Freeze
You can remove the Dancing Rune Weapon with something else for non tanks. Perfect for interrupting (I'm using it by the way).
