This bugs me too. I haven't levelled a single one of my jobs through roulettes or POTD because facerolling the same easy combos just fails to capture my imagination as a player. My friend lives and dies by roulettes and has probably spent 50% of his total playtime in Tam-Tara Deepcroft with three other veterans, all spamming 1 and 2 while watching Netflix. I always end up telling him how things work because he ends up with multiple endgame jobs and no clue how to use them effectively, but even then I'm mostly soloing and while I read the tooltips and practice, I don't get practical experience of some group skills until I party up and learn. Positionals, for example, cannot be learnt properly solo or in faceroll content.

Maybe just a big bonus to experience if you're on a level-appropriate dungeon to provide a viable alternative to the roulettes for people who actively want to play at level? Roulettes would still offer bonuses and a lazy option for those who enjoy the syncing, but those who want to push themselves a bit harder I don't think roulettes should be the pinnacle of party play.

Even then though, dungeons are depressingly easy. A bonus for playing at minimum ilevel (or some as-yet unimplemented harder difficulty)?
