Monk actually is pretty damn good where it is but it suffers from a few half-baked ideas or under-utilized skills.
The issue monk has is that it can't fully capitalize on its new bread and butter; the beast chakras and more importantly; Phantom Rush.
See they changed brotherhood and riddle of fire by separating them by 30s on their cooldown in opposite directions, still synced but left apart mostly so that you could use your riddle of fire midway through. They gave perfect balance 40 seconds on its charge's cooldown to sync it with brotherhood. The problem is they didn't really think about how the opener should look like because it leaves your phantom rush in a weak spot that forces nothing but bad habits for the player. This caused balance rotation players to develop the infamous "double phoenix" opener rotation that though gives the optimal damage, downright bastardizes the design of beast chakras. The numbers don't lie however.
Let's think about it though. The main issue is that you can't really even use their phantom rush soon enough so their "opener" takes nearly 110 seconds to finish.
People have suggested to just slap another charge onto perfect balance because it'll let you get the phantom rush out sooner, But once you use all 3 charges, you'll be back to juggling your rotations til you have another charge available again, It only saves the opener and doesn't assist the rest of the fight.
Anatman. It does the same thing in one gcd and a server tick, as you could do in two gcd's while remaining fully mobile. There's no reason to use it under any circumstances, it doesn't even hold leaden fist, perfect balance, or blitz countdown timer. What can it do..?
Honestly it's kinda a surprise they didn't do this from the getgo, but they coulda just made anatman generate the 2 nadi's over time under a punishing requirement so it's optimally used during prepull, whenever monk is too far away to attack for long enough, or whenever there's a long transition.
What this would do is it'd allow you to bring your strongest attack into the party's buff window to smooth out your opener, it'd eliminate double phoenix, and anatman would see universal use without it being too broken. Honestly I don't know why they haven't attempted this already. It'd be the equivalent to Reaper's Soulsow, or Samurai's Meditate. It just seems right. It should be gospel to never go halfsies on a change if you're going for something specific. They better go all-out with it.
So yeah; Make Anatman charge nadi's. Make it punishing to use mid-combat to discourage it being put in rotations, Make it do it one nadi at a time so that if it is used mid-combat it's fair and doesn't take away from the pb charges. Except out of combat, make it almost instant for both nadi's during then so it's got use in dungeons/raids/singleplayer content.
Monk should be kept busy, They lost a lot of their ogcd's and positionals so the most they could do is give them more options.
