They made Monk unique. But that uniqueness in SB is more of a hindrance now due to just how short the form timers are and that then has an impact on refreshing your GL. Because the GL timer is also the shortest outside of enochian, but let's face it, you can just hit transpose and never have it fall off. and if it does fall off, well just hit that enochian CD again. Not really the same case for Monk due to PB long timer. Also with ToD and Fracture being removed everything we do now is locked behind a form. the One Ilm punch stun and AotD silence. Locked behind forms. Not only are they a potency loss to use, you have a 1/3 chance to use them when needed. They become unreliable and also an actual hindrance on dps due to, again, our buffs and debuffs being so short. 15s for Dragon Kick and Twin Snakes means you either miss refreshing those, OR you miss out on your 2 strongest attacks GCD attacks (not counting the Demo DoT), bootshine crit and true strike. This is why forms are a mess. I think previously it was just easier in HW to just accept that OIP and AotD(except for aoe) were useless. But we also got new DPS abilities to hit so it didn't feel like too much of the same thing.
But now that we've had ToD and Fracture taken away we're stuck with an even more boring rotation than we did in ARR. As someone above said the devs don't really design fights with Monk in mind. If a drg and nin can go into a long phase change and come out with their buff resource still in tact. A monk should be able to as well. Afterall a monk doesn't even bring the level of dps a drg and nin bring to the raid, nor are we the kings of dps anymore so why are we still punished as if we are? I don't see sam getting punished at all and their downtime is by far the easiest to handle, sure they can drop their 30s buffs and debuff. But if the downtime is long enough they can just meditate and hagakure so they don't need to overwrite any sen when the boss comes back. Sam actually does extremely well from a phase transition. Monk can meditate and... form shift for 1 instant GL. Not exactly much compensated compared to what they just lost. Anyway I rambled, sorry :P
My changes:
Perfect Balance: CD reduced to 60s
Riddle of Wind - Grant Double Auto attacks for 10s / 120s CD
Riddle of Earth - Raid Wide shield for 6s / 120s CD
Riddle of Fire - Raid wide damage buff (5%) for 10s / 60s CD
Brotherhood - Removed
One Ilm Punch - Taken off GCD and forms. Grants 5 Chakras / 120s CD
Deep Meditation - changed to 'Enhanced Bootshine' - Grants a Chakra every Bootshine crit.
Tackle Mastery - Grants an extra tackle at 0 potency after using shoulder tackle. 20s duration buff. (would help with mobility)
AotD - Potency buffed to 100. TP reduced to 100. Silence Removed.
Tornado Kick - No longer removes GL3. Instead uses 5 chakras to deal AoE damage in a frontal cone. Potency reduced to 250
Additional Changes~
Greased Lightning and Form timers. Increased to 30s
All Potency nerfs going into SB reverted back. Including the Forbidden Chakra
This puts our CD alignment the same as every other job that has burst and also synergizes us with NIN. While not being equal to Nin, we at least offer consistent 60s damage utility and would not be such a hindrance if there was no nin and also to jobs that work in 60/120s burst windows (which is the majority)
Numbers can be tweaked but I think the job would feel at least a little more playable, less punishing and more fun and also cut out the RNG gimmick. But that's just my opinion
