Personally, I can accept the 6.1 changes in NIN, especially it boosts personal damage and overall you just need to re-adjust the timing of 'mug' to synergize with other party members.
But looking at all of the job adjustments, I also fear that the unique point of each job might disappear at some point. somehow I feel a strong will to standardize things.

True, adjusting each skill that is similar to each other into 1 standard, make it easier for players to adjust their playstyle when changing job.
but it will also quickly become boring and the uniqueness of each job will be decreased, I prefer skill that do slightly different (whether might be better or worse) but represent my job properly
as long as the overall balance is good, I don't mind some unbalance on each skill (e.g. i don't mind my AoE have lesser area or damage than other jobs)

True, it's good to synergize your team rotation to the same burst window. but I feel better when players can somehow align the burst window with their own coordination.

True, RNG can sometime annoying. but in my opinion it is something that generally accepted to exist in a game, and it is also what makes each run feel somehow a little different.

In conclusion, I already respect the developer for their efforts to balance things out. it is difficult to find a proper balance, but I hope each jobs can still have their unique point stands out.
