My only issue is I really don't want to spam roulettes anymore, and that's kinda the easiest way. It's just that after 11 years, I just don't want to anymore.

It's not as bad in EW. In EW, it felt like getting to 85 was a chore. After that was much easier, but getting past 85 made me want to stop doing it a few times. But I haven't had any issues from 90 to 100 besides general boredom and the woes of leveling up in synced combat, so your class never changes. But that's more an issue with the game in general rather than a complaint towards the leveling experience.
