NIN/MNK difficulty?

[Allyrion]

Tbh the best way would be to try it out for yourself since "difficulty" is subjective. My static MNK mate for example finds that MNK is the easiest meele job out of the 4. He plays all 4 melee jobs and usually pulls orange numbers at fflogs with his MNK.

I don't get though why nearly every thread at the boards here have to end in a Job X VS Job Y war... when it's more a personal thing...
Everyone has a different opinion and feel about "what's more difficult"...

I completely agree. Difficulty generally depends more on the player, playstyle and just how your brain works.

The differences in percentiles are mostly an example of how punishing the Jobs with mess ups or mechanics/movement. With MNK, there's less thinking involved than SAM or NIN, but if you miss positionals or lose GL3 then you're heavily punished. Even if you mess up on the 'easier' jobs, you still do well and thus the disparity is smaller with the top end despite there being more ways to optimize.

You should really try them out yourself to see how well it flows to you.
