Why do jobs need to be changed around people being unable to read tooltips or learn their class? Bc no matter how much you trim away for the sake of 'ease of access' you're always going to have a bunch of people who just press whatever buttons they like in whatever order they like, and get through every piece of sub extreme content just fine bc that's how the game is designed.
If you design classes around people who don't want to or care to play the classes the way there were designed, you are eventually going to end up asking yourself why you're bothering to design them in the first place. The fact that I still see people screwing up classes like summoner to this day just tells me that theres no sense in endlessly simplifying jobs bc they will never, ever be simple enough for the apparent target audience.
