God o5e's Monk is such an insult to game design, which tracks given how much it was trying to go back to 3.5.
Stunning Strike is hands down the most powerful ability they get, and anything else that uses Ki is, as far as effectiveness goes, incredibly niche at
best. Meaning that Subclasses that focus on giving more things to do with Ki, are just wet noodles. Yes they keep designing classes based on more things to spend Ki on that are definitively worse than Stunning Strike, main exceptions are Kensei and Shadow. Kensei gives a lot of passive buffs which is nice and Shadow Monk gives cool Ki-less stuff and access to the spell that makes Stealth characters redundant.
The damage dealing is a JOKE. Most front liners get a choice of fighting styles but Monk is forced into Dual Wielding. Which is one of the less egregious problems but is context for how little they get. Flurry of Blows both costs resource on a per use basis, and can MISS. Every other "I'm not a Fighter" buff is bonus damage on first hit, Monk gets the unique position of getting to pay to miss. Barbarian Rage you pay for but it's for every hit in a combat, and Battle Master Maneuvers proc on hit so they always get to do their thing.
"But I had fun!" The Monk Class Fantasy is amazing, yes, but mechanically they amount to an audience bystander that gives a few free Hold Persons per Short Rest. To be fair, this isn't a problem unique to 5e, this was something that's been a problem since at least 3.5 (except in 4e, naturally) 5e just embraced and amplified all of 3.5's problems aside from fiddly numbers.
Adept though looks NICE though. Stunning Strike is still an option, which is still strong, and even has an upgraded version in Paralyzing Strike, but the playing field having shifted changes context a good amount. Other Martial Classes can Stun so it's less unique, you can choose to take other effective options instead so it's not just always hovering there as a better usage of actions than whatever you built to do, and more Classes wanting a Short Rest should hopefully help to curb how quickly Adept can Nova through their points.
A couple builds seem really appealing to me. Kensei gets a lot of fun tools, like the Hook Swords, and I don't think it would be a heavy ask to allow Adept Weaponry combined with Kensei to allow a Glaive/Naginata wielding weapon master but that's not quite RAW due to system differences but not game breaking. Stunning Strike, Paralyzing Strike, and Pressure Point Secrets on an Astral Self Adept, combined with more points early on, means a WIS Monk is a much more viable build requiring a bit more resource management to sidestep being MAD with potentially great payoff.
Monk needed the most love and DAMN did they get it
