Your FC should be buying/using the Meat & Mead II food buff during raid hours, that extra 10 minutes covers it and saves costs.
CD reset on wipe is a bit of a challenge I'll bet in the current coding, and because of possible abuse of the system and instances. Although maybe they should make the conditions for CD reset when full-party wipes in a raid instance, and cannot be re-applied again for X minutes. Easier compromise but probably easier said than done too.
