Hey there. I am interested in a discussion to gather some objective and argumented PoV onto the difficulty of playing Mnk or Nin. I am leaving Drg out of it as they are getting changed quite a bit very soon, and that Mnk and Nin are currently fighting for the spotlight.
Some people have argued that nin dmg needs to be nerfed because their damage is "too easily accessible". I do not have a mnk leveled up (disclaimer), but i do main ninja, and i did invest some time to understand the rotation of mnks well enough.
I am quite unconvinced by those claims, and while i don't think nin is harder to play than mnks, i do not think there is a huge difference in difficulty between the two, and certainly none that warrants a nerf when nin is already the one with lesser damage and utility (although very slightly on both accounts).
Mnks need to maintain a 30 sec Dot (like nin), a 18 sec dot (like nin), a 15 sec damage increase buff (like nin but nin can slack on that if a warrior do it for them, and it's actually 20 sec long), and dragon kick. GL will be kept up as long as you continue hitting the boss in a non-stupid way. On top of that, they need to hit positionnal attacks to get the most out of their attacks, although missing one here and there won't make or break their dps, since they get all the other benefits anyway.
Ninja, on top of the listed things, will need to use goad effectively (can't wait for someone to call for it as it is a waste, for best use you need to pretty much keep it on CD and organize with your party for who gets it when), and use jutsus in a correct way. Most people think this is simple, but there is quite a lot of thought involved in it: you do not want to make huton drop, and it last 70 seconds. There are 20 seconds of recast for justus, starting at the execution, and you need some time to input all mudras. Realistically you have at most 5 seconds of margin to split in your cycle of 3 jutsu (huton, suiton, raiton) if you want to prevent the drop of huton; if you have kassatsu, you have about zero margin and need to hit all your jutsu instantly. You need to input them without double tapping (or you can bunny, and you need to watch for any delay in the execution), and need to know beforehand which of the 3 you need to use. Trick attack is also better saved for the next jutsu if the boss will become untargettable in the next 10 seconds, so you can not just blindly go huton -> suiton -> raiton, sometimes you will switch to huton -> raiton -> suiton and back again. All this is quite an involved thought process and is far from trivial -- it is honestly harder to keep track of than simply "blue dot about to fall off, time to shadow fang", which you can do "on the fly": i hit the first part of the combo, and check for what i need to continue with during the off GCD. I can't do that with my jutsus -- if i do not check out some seconds before my jutsu is ready i will likely either delay it a bit too much or just use the wrong one.
When all is said and done, i feel like the jutsu complexity does make up for the positionals and then some, and that both jobs feel equally complex to play out. However, when reading stuff on the forum or reddit, it seems quite a large part of the playerbase feel like ninja is braindead and mnk is rocket science. What's the take of people here ? Care to elaborate on the subject a bit ?
