I think that food (mats used and the buffs) need to be looked at and adjusted. As it stands, the time invested to gather materials and craft the food do not even come close to the gains they provide.
For a basic item like La Noscean Toast, 10 different items are needed from all over Eorzea. The travel time alone is getting up there towards the buffs duration and when the time it takes to do the 7 steps to craft it, you are pushing close to the actual buffs duration.

In my opinion, the current setup for what it takes to get the materials and craft foods versus the buff itself only encourages botting or RMT. With the changes to gathering experience and leveling speed, the behind the keyboard time invested does not even come close to the market value of the materials.
