I decided to run a quick test on Cooldown.
First off it's a 10 minute ability and it automatically targets your Auto.
After activating and quickly building up maneuvers to force overload, using the ability completely erased overload. I can't really tell if it is a set amount of burden that it takes away or if it removes all burden completely.

Seriously, you won't be @#%^ing happy until SE releases a full sized Bahamut avatar you can @#%^ing ride and use to kill players that annoy you, one shot AV/PW/Shinryuu, and burn the FFXI nations to the @#%^ing ground for fun. All while actually restoring mp used instead of costing any.
