I did give an example as to why it's ridiculous to imply difficulty should have no reward. It is not my fault you are daft. The community has actually spoken out about this before. It's why hunts have never given gear or upgrade materials that equal raid gear ever again. I also find it very convenient that you just keep sidestepping my comparison to EX primals and raids, yet think it's totally ok to do for jobs.
SE needs to realize that "uniqueness," is a poor excuse. In a collection of silverware, the broken fork is unique. The broken fork goes into the trash. You cannot balance on uniqueness and feeling alone. No game does this. Even in your WoW example, it does not follow that philosophy at all.
While you may say it is "normal," for it to be that way, I've yet to see any MMO have this aside from FFXIV. Even in your example for WoW, you never specifically stated what it actually meant, you just stated one class was easier than another, therefore it is true. That is an incredibly vague and quite frankly meaningless statement. It's not an example at all. I don't play WoW, if you want to convince me or even support your argument stating something so obvious, that two classes have varying difficulty, is not enough. I have no way to determine whether or not the two classes perform equally, or that neither is rewarded more than the other as you so desire.
You seem to be misunderstanding my opinion. I am not saying that there should be no difficult jobs. I'm just saying that SE is going to find it impossible to convince the grand majority of people it's worth playing a job if it's difficult just for the sake of it.
As for playing a job just because you find it fun, that's all well and good, but when people start to underperform because of job difficulty, unluckiness with mechanics, or feel like they could contribute more to their group with a different class, then that no longer applies. There are plenty of people bent out of shape about DRG especially for this. Lots of "Why play DRG when SAM exists?" posts going around. Some people love DRG and find it to be a blast, but also have more fun actually contributing and doing something.
This is exactly what I want. In two different situations each type of job has more effectiveness and/or is stronger than the other. In situations classes with low risk can dominate during mechanic-heavy or movement heavy fights. In certain situations classes heavily influenced by mechanics and/or movement can dominate since the boss is sitting still or they're not required to move much. I thought that would just be common sense.
