Monk Needs a Complete Rework

[ValStormbreaker]

Part 2:

The amount of work needed to implement all this stuff, and then rebalance the job, is just way too much work and cost to be reasonable, especially because it has to be balanced with a) every other job in the game, and b) every encounter design. You're getting wayyyyy ahead of yourself here and asking for the Taj Mahal. It is infinitely more likely for quick and cost-effective solutions (i.e. "this thing can be implemented within the hour and we already have all the assets/animations/icons/effects done for it") to be implemented over these requests. And that's pretty much a running theme with this post of yours.

It is simpler to just say "put this one oGCD into the game," and for that, see my prior post about Axe Kick, which already solves a lot of problems.

Add a filler chakra cost for ST and AoE.

Unnecessary.

Have TK proc from GL upkeep for however long (30s?).

Making TK a proc-based ability instead of a meter-based thing goes against the spirit of MNK as a martial arts job. The meter makes it more like a fighting game. Changing it to a proc-based ability is antithetical to the identity of the job.

Move chakra building to certain positionals (true and snap as they have no extra effect) and have it increase linearly instead of RNG.

I'm not the biggest fan of the RNG but chakra gain issues are some of the most minor with MNK right now and tying them to positionals instead of them being critical hit based, when we have guaranteed critical hits from BS and very predictable points in the rotation where we can expect a chakra gain, sounds like a nightmare to both play and balance.

Remove chakra gains from Brotherhood, make BH 5% damage buff to all.

This is a terrible idea, because chakra gain during Brotherhood gives MNK something more to do and allows for more weaving opportunities, which is where the fun factor of the job comes from, and it would totally nerf damage output in the burst window. BH can't be a 5% damage buff to all, because then it creates balance issues with DRG's Battle Litany, and pretty much any buffs from NIN, DNC or BRD. The amount of time and resources needed to rebalance the job would be absolutely staggering so the likelihood of this ever happening is nonexistent. A better idea would be to take the stacking effect of Meditative Brotherhood (which is listed nowhere on the tool tip but is indeed part of Brotherhood as of 4.3) and remove that, and instead double the percentage to 60%. At present, a stacked Brotherhood allows MNK to have tFC with enough of a frequency that it adds a tremendous degree of fun to the job, nearly making up for the lack of oGCDs.
