Just a suggestion since we can carry 500 JP after Mastering a job, think the devs would create special BCNMs that require say 50JP per KI, and can only be bought and entered by players with mastered jobs, this would give us a reason to go to JP parties after mastering. Just like merit BCNMs but with much better rewards, possibly a random piece of JSE gear that can only be worn by mastered jobs? just something to think about.
