I choose to be optimistic and interpret this as "Lots of categories will have increased caps, but only the 'Other' category will have the cap increased for individual items." Having 15 merits for each Job Specific category would be pretty awesome.
SE will probably take the opposite stance when implementing the changes, giving me 120 more MP and little else when the update rolls around. Hope is the seed from which disappointment blossoms and bears it's bitter and poop-tasting fruit.
