From what i understand, it makes the macro priortise that spell, so as soon as cooldown is finished it will cast cascade.
I may be wrong though

It has nothing to do with priority or anything the like. It only works on spells that you toggle on or off, like a Combat Rogue’s Blade Flurry. If you just put /cast Blade Flurry it will keep toggling it on and off. If you put /cast !Blade Flurry, it will get toggled on and stay on until you or another macro turns it off. This works well for classes like the Combat Rogue as Blade Flurry can be put on a separate AOE button with /cast !Blade Flurry at the beginning. To toggle off on a ST macro, you would use /cancelaura !Blade Flurry at the top of that one, which would cancel Blade Flurry then ignore until it’s back on. Hope this helps you out some. Panda
Lets say your playing a druid. lets take the spell Cat Form. so this is what cat form does.
Cat Form Shapeshift
7.4% of base mana
Instant
Requires Druid
Requires level 6
Shapeshift into Cat Form, increasing movement speed by 30% and allowing the use of Cat Form abilities. Also protects the caster from Polymorph effects and reduces damage taken from falling.
HERE >> “The act of shapeshifting frees the caster of movement impairing effects.” <<
like Pandabomb said. " it will keep toggling it on and off " with just /cast Cat Form
so every time you press the button you will go into your normal form , then into cat form and so on.
if we changed it to /cast !Cat Form now you can spam the button removing the movement impairing effects, but stay in cat form
