Suggestion: Duty Finder Revamp?

[Iscah]

Or just cause all enemies' and dungeon completion experience to generate exp as if they were your actual level, rather than your synced level. Or, give some portion (say, 75%) of that.

That sounds like a great way to encourage people to game the system so they only get low-level roulettes if they're going to give you the same EXP for less work.

They should take out MSQ roulette and make it solo, like you said, and put the XP into other roulettes.

MSQ roulette isn't taking up part of some overall quota of roulette rewards. They increased it without deducting tomes from elsewhere, and if they remove the roulette entirely then that reward most likely goes with it.
