I mean its literally the only setting for that graph where reaper drops from rank 1 to 2, and things like kill time/crit rng/party team comp all play a much greater effect when looking at only max rank, do you really think its a good idea to balance the game around that? I am not saying max rank doesnt mean anything, just that ranks from 95 - down are much more applicable to the average playerbase, and i think you already know what those graphs look like.
I am not 100% sure about monk, but from my understanding the rotation/opener its currently doing is something the developers did not think about and it makes it so they do way more damage than intended or something, not really gonna talk about it since i dont understand it.
Second of all, since you played wow i am pretty sure you realize how unfair it is for the best or in very limited scenarios probably not applicable during progression, second best damage dealer to also have the best utility skill except instant raise, while also being pretty easy to play.
In the end it just comes back to this, what is the point of playing something like dragoon or ninja, if they do less rdps, have no party utility, animation locks, and are also harder to play on top of that? Outside of the obvious "because you like it/have fun" which is true but also invalidates every balance issue ever.
I think for how streamlined the game is, no talents, no legendaries, stats have similar effects for all jobs, no trinket effects, the balancing could and should be better, i really dont see how you can argue for one job to be best at everything, there should be different upsides for different situations, as it is right now its not good.
And chill with the hyperbole, absolutely no one is asking for gigantic nerfs that make the class unplayable, i wanna play some reaper myself aswell, i'd just like to see the margins tighten, if ninja/dragoon/samurai/reaper were all within 1% damage wise reaper would still probably be the best option because of party healing, which is something the other melees just dont have access to, except monk's mantra which is also on a longer cooldown and weaker.
I also have an inkling you'd like square to not watch these forums until the job you like playing is the one on the undertuned side.
