How is monk after the rework?

This sounds less satisfying and fun than the current iteration of the job where you work toward bootshine as the big damage attack.

That depends on how it's situated. Personally, I found Dragon Kick in the context of ARR and StB gameplay (due to Demolish's duration at those times allowing for Dragon Kick to be dropped just before Demolish and its own reapplication in exchange for a Bootshine and True Strike to notable net potency gain) more interesting than the current Leaden Fist combos.

I also don’t see how it makes the monk more about the form based combos since there’s still gonna be an optional rotation to stick to, just without the satisfying bootshines.

Again, the past (and especially the StB Riddle of Fire slow-down) has done this part better, as optimal play then often tended to itself rotate between different rotations, while further changing more or less on the fly based on add spawns, number of DoT targets being maintained, and forced downtime.

And if you don’t like perfect balance, suggest a better version of a burst phase. Saying it’s just spamming bootshine is still kinda disingenuous, but if you wanted to make it more complex to build towards a big attack that could be cool.

For my part, Perfect Balance was a plentifully interesting mechanic back when it offered distinct advantages in AoE, utility, and ST throughput, and especially when those throughput affordances depended on one's other abilities and starting form (e.g. Riddle of Wind, Coeurl form). If anything, it was the siphoning of AoE potency from Rockbreaker to other (new) AoE GCDs, the loss of our utility, and the removal of our core mechanic so devalued that pinnacle ability, not any flaw in the concept itself.

But, of course, I'm the in the apparent minority who actually liked Greased Lightning as a mechanic, perhaps most especially when it was a challenge to maintain (e.g. Brayflox HM speedruns, T10, etc., back when it had only a 10s duration), and would rather not have had the job's core mechanic gutted rather than revised and polished, let alone on a vague hope that, contrary to all recent job designs, we'd get something interesting in its place.

That said, it's not disingenuous to say that PB is currently Leaden Fist spam. Optimally used under an ideal GCD length, it is.

They should just let the guy who designed Tifa gameplay from FFVII remake to do the design for 6.0 MNK.

Sadly, I doubt much of the spectacle of that system would carry over to one where it's very obvious you're just punching vaguely in the direction of a generic cylinder unaffected by your actions, in place of VII-R's in which the actual timing and geometry matters.
