If you've never played it before, it's OK. A lot of the complaints is that Monk has regressed significantly since its inception with almost nothing to show for it, but it's still satisfying enough to play on its own.

For people who've played it for the better part of a decade, it's essentially just a worse version of 2.0's monk. Or 3.0's. Or late Stormblood's. Puts out great numbers though. Honestly if Monk wasn't one of the strongest jobs in the game right now I don't think there'd be many people playing it at all.
