Monk Needs a Complete Rework

[Sora_Oathkeeper]

I don't know if a Twin Snake duration change would be really necessary (or if anything a slight increase to 16s would be fine) and being on a 30s cooldown (even on a sks based one like GNB's Gnashing Fang Combo and DoT) is likely not enough. You would want to be using the filler gcd enough times every 15 seconds that TnS won't fall off.

It's not really about Twin. The problems with no formless GCD that has rotational use causes desyncing issues with Demo and RoF. Currently it's better to do 2x Dragon Kick throughout the rotation to realign RoF with Demo, iirc it's every other RoF as the gain from getting 2 demos under RoF without clipping is a pretty substantial gain.

The Twin change would need another 3s. Currently Twin falls off for its reapplication under the 2 true per twin rotation. Adding a formless GCD would set that back by one GCD, resulting in needing another 3s (to ensure the buff is up for the reapplication aswell). Not changing the buff timer would result in awkward 2 trues per twin but only when OIP/6SS isn't coming up.

Tbh I would rather MNK take ideas from GNB and NIN.
Continuation ability on MNK would feel great imo and keep to the core of feeling fast.
Remove TFC, re add it, Haymaker and OIP as add them as part of continuation, with TFC being the finisher to it. Make it all cost 5 chakra, increase max chakras to 7.
Add a filler chakra cost for ST and AoE.
Have TK proc from GL upkeep for however long (30s?).
Move chakra building to certain positionals (true and snap as they have no extra effect) and have it increase linearly instead of RNG.
Remove chakra gains from Brotherhood, make BH 5% damage buff to all.
Remove potency from Leaden fist and spread it more evenly across the rotation, it's ridiculous just how much of MNK's damage is backloaded into Leaden Fist Boot and TFC...
Remove fist stances, they are just an illusion of choice. Even in prog Fists of Earth is crap.
Lastly I'd rework Anatman to give 1 or 2 stacks of GL instantly with no channeling.

These are just off the top of my head but it'd make the job faster without button, keep damage more consistent due to lack of RNG and have rewarding phases of TK for GL upkeep and 'continuation' for positional landing.
