Just want to add some MNK suggestions too. Let me know what you think.

TL;DR:
-scrap/rework useless skills/traits
-improving raid utilty (a bit)
-reducing rng factor
-merging GL and Chakra system


Fists of Wind - scraped
Fists of Earth -scraped
Form Shift - scraped
Riddle of Earth - scraped
Steel Peak - scraped
Tackle Mastery - scraped


Fists of Fire - reworked to passive trait
One Ilm Punch - reworked to a ogcd attack with Cd, gaining 1 GL
Riddle of Fire - reworked to increasing attack speed by 15%
Brotherhood - reworked to increasing dmg of nearby party members; still have a chance to grant 1 Chakra if party members execute a weapon skill or cast.
Perfect Balance - reduced Cooldown
Deep Meditation: reworked to when gaining new GL and GL3 is already up, 1 Chakra is gained instead.

Tornado Kick - reworked to Hurricane Kick.
Effect: Using up 5 Chakras to deal physical dmg to all enemys in a frontal cone.


New traits:

Double Courl Fists
Effect: Changing Shoulder Tackle into Double Courl Fists
Double Courl Fists: Rushes towards an enemy, inflicting dmg to it and all enemys in the way, stunning the Target, gaining 1 GL.

Pure Will
Effect: If GL runs out by time it sets automatically back to its full lenght. Has a Cd.

Inner Focus
Effect: While not in Raptor-Form or Courl-Form, Opo-Opo Form is automatically gained.


How the MNK would play:
It would still be the same thing. Collecting Chakra with Meditation before a fight and between boss phases, then start with Dragonkick right in Opo-Opo-form (or use PB for opener). Proceeding with your combo till you got 3 GL. Each time you would gain GL beyond 3, the GL timer sets to max again and 1 Chakra is gained. 5 Chakra can be used for The Forbidden Chakra (single dmg) or Hurricane Kick (aoe dmg).
New brotherhood, Riddle of Fire, OIP and Double Courl Fists help gaining GL and Chakra faster.
At moments you can't hit anything, Pure Will provides GL to just fall of.

As you see, most of it is QoL. Balancing can easy be made by reducing/increasing dmg/cooldowns, or by changing single aspects of skills/traits.
(e.g. OIP/Double Courl Fists dont gaining GL3/Chakra)
