There were some excellent suggestions in the beta forums for the current expansion for things like a proc for the guardian and his moderated target. I remember some.
1. A proc that would drop the moderated target to the bottom of the hate list if they made it to the top. This would make a fun push/pull game for the tank and moderated target.
2. Few other procs ideas for same scenario: an xfer, a short buff, etc...
3. General buff for tank/target on top of the current buff
IMPORTANT: AFTER THE REMOVAL OF THE ADC DEBUFF
