Monk:

Changing the job from consistent high damage to a job centered around RNG is kind of not great. Also comparing the implementation of the RNG aspects of this job to other jobs also relying on RNG (Bard) just feels bad. Bard get a 100% proc rate on their critical DOT ticks, and for all of their songs even one crit is added DPS. Monk has it's abilities buried under layers of RNG with only a 50% chance to open a chakra when you have a crit weaponskill which means you have to have the RNG of getting a crit and then the RNG of did you get a proc, and after that you still need 5 procs to use them.

Tacklemastery is still a joke. Wind Tackle is marginally useful, but earth tackle still has no use in any content.

Riddle of Earth still isn't working well for monk as the skill is at odds with the toolkits of other jobs. If you get hit by an ability, but take 0 damage thanks to a SCH/AST shield you don't refresh your greased lightning, not to mention that this skill encourages you to take what might have otherwise been avoidable damage just to try to keep up your greased lightning.

Beyond that, the job is still putting out good damage, and isn't the joke job getting left out of content like it was in Heavensward, so at least things are improving. Just feels like they didn't put as much thought into the job as some of the others when designing changes for the expansion.

Ninja:

The addition of ninki is a fun mechanic that doesn't take much thought to execute as it just builds on its own as you auto attack. Only suggestion would be to have skill speed increase auto attack rate instead of auto attack damage to make the mechanic more interesting, and give the player more control on how much of the resource they want to generate.
