Each role should have Easy, Mid and hard/complex job when it comes to it's rotation.
And they all should be rewarding when hitting your buttons correctly. But the hard/complex jobs should reward a bit more. Either in damage, utility, etc.

The problem I have is there is that they're simplify jobs while also doing the same to the encounters.
And yes I know they have ult for hard encounters but that doesn't fix the job part.
There should be a flow of easy to hard content and easy to hard jobs. And they aim the easier one towards new players so they're not overloaded.
