I play pretty much DRG and MNK in FCOB on t13, and monk is not as stressful as he said to me. As I said, everything is subjective. Is it stressful for you? Yes? Not for me. Its pretty smooth, considering the melee friendliness of Fcob and the low downtime you have. And lets say here, Raid content is where it matters when you want to enter the competitive dpsing, and know what a job can do. Melee have it extremely easy right now, and old contebt such as primals, while it's true that they give you a little of downtime, is still no more relevant. Also grease lightning is 12 seconds duration total, knowing that a GL3 stack monk can do his combo in 6 seconds, you have plenty of time to reapply your stuff.

As I said, while it's right that MNK have the most positionals, it's something that should be Intuitive as a melee dps, a no-brainer. And honestly, even if you cannot hit a position for X reasons, it's not the end of the world. Yes, it's not optimal, but doesnt keep mnk away from top dps for missing a couple of positional, and best exemple is probably t11. And I think its not exaggerated to say that most people agree: Monk is not RocketScience, it's punch and move. Moving is what you do all the time in this game.

The oGCD of a monk are: Steel peak, Howling fist, b4b and internal release. Rest is GCD, which is up to you to apply as you wish.
