Though I've only recently starting leveling MNK, it seems to be a job of contradictions. You build up Grease Light to improve DPS then spend it for a Tornado Kick. You stop DPS to push Mediate only to do a meh DPS attack. Just a weird way to do business.

The two key features that standout for me are GCD speed and abundant requirement of Positionals. That is what really makes Monk unique and that is what should be built on.
