In my opinion, Ryunohige is as good of an example as it is bad, all jobs have Mythics, its just one that truly makes a job stand out, the same can be said for a Kenkonken PUP, because with a KKK a PUP is a force to be reckoned with. However Black Belt is just a quested piece of JSE, so I would expect other jobs to get the same kind of thing, with the same kind of difficulty. No 1 Mythic is easier than another, so really I don't think the difficulty with these should be different. Another thing on why this should be done is MNK is getting another more powerful Black Belt with SoA, which means even more powerful of a piece of JSE. But I will agree, SE would have to make them have stats for what the job needs, and thats not always what SE seems to get so well.
