Why should they change it? Do you want to prevent yourself from using it at a bad time? If so use a variation of this Macro instead:

/ac "Rage of Halone" <t>
/ac "Shield Lob" <t>

This simple Macro makes it so that when the target is within 3y of you it gets hit with a Rage of Halone and if it is outside of 3y you Shield Lob the target.
