I'm gonna get my MNK to 90 today (89 atm) if I manage to get in but here are some things I noticed:

-Bosses move and turn a lot making positionals more annoying to achieve and using TN only band-aids the problem
-Removal of positionals is mixed. Personally I would have kept it but removed the chance of gaining chakra via cirts/bootshine and move it to hitting positional exclusively (no potency increase). That means that if you hit those positionals you get one charka regardless of crit removing the RNG of chakra gain entirely, outside of brotherhood.
-Riddle of Earth is questionable since it suggest that MNK should be eating pointblank aoes since the dmg reduction is very strong (60% at 3 stacks). I guess greedy MNK's will appreciate it and healers adjust.
-Thunderclap is my only real complaint. It needs a target to dash to but if that target is out of range then you have no dash. IMO it should work like DNC dashes because atm its clunky, especially on controller where in full parties its very hard to target a party member to dash to.
-Perfect Balance being on 40 secs is bad since your opener is scuffed. It either needs a 3rd charge or 30 sec cd to line up with RoF.
-Six-sided Star is still terrible to use.
-Anatman needs to be on a shorter cd or do something else like reduce PB recast timers while in anatman.

These are the only issues I see with the class so far in majority of content, i.e. dungeons, MSQ, open-world, etc. I'm sure it will change slightly in the 6.05, or at least I'm hoping, but thunderclap is really my only issue with the job. I've been in countless dungeons where the tank is mass pulling but is so far ahead that I can't dash to them. Yes you can dash to the adds in most cases but you will still be behind. If they changed it to work like DNC it would be much easier to stay in the mobs and aoe rather than at the rear where you will only hit one mob.
