I agree with your post. I'd like to add 2 more little tidbits though, both regarding Deep Meditation and one with Brotherhood.

1: 70% chance on crit is awful. It's not that it's too low, it may average out to be the exact number we need but it's going to *FEEL* awful. Now when you use Bootshine or get a couple of crits in a row it's not "oh good I got a chakra!" it's now "damn it I didn't get a chakra..." It may simply be a perception thing but I know for sure I'm going to notice when I don't get chakra stacks a whole hell of a lot more than I do now. Buff it to 100% and nerf TFC and Enlightenment appropriately. Any RNG chance above 50% shouldn't be a thing in these games because it feels like you lose when it doesn't happen, versus winning when it does. It'll also give monks more buttons to push organically, helping them feel like a faster job.

Funnily enough this reminds me of SWTOR beta, where Vanguards had a 70% chance on ability use to get a stack that stacked to 5 times to unleash a super strong attack... huh. Weird.

2: They said they wanted to reduce the interdependency of jobs in Shadowbringers -- for example, Bard no longer essentially requires a Dragoon to function, as there's no more piercing debuff and their DoT procs aren't based on crit chance. This is good, now a bard isn't attached at the hip to a Dragoon or, to an extent, scholar. In fact, none of the DPS really require the others... except monk. Monk is still based off crits, which means a monk requires the even-nerfed Battle Litany and Chain Strategem to get the most procs, not to mention the still-present requirement that Monks be paired with as many physical DPS as possible to get use out of Brotherhood. Oh sure, Dancer requires another DPS to get the most of their skills too, but Dancer can pick any DPS (or, hell, if needed a tank or healer though that's not optimal) and they themselves won't change. This isn't even necessarily a problem that Brotherhood only boosts physical damage for the raid; a little variety in buffs is nice. The problem is that Monk alone requires certain raid compositions to function at its peak due to Brotherhood still only working off weapon skills.

If Brotherhood was changed to "X% chance when a party member executes weapon skill or magick attack" it would function a lot better, and there's even a new precedent since that's how Dancer's espirit works. Fixing Deep Meditation could be as easy as making it a flat 30% chance on weaponskill use. Currently chakras being crit-based feels interesting because of Internal Release, which didn't just result in bigger numbers but also more buttons due to more chakras. A flat percentage chance would probably go unnoticed by most players, and would mean Monk isn't as tied to Dragoon or Scholar.
