There's no difference between MSQ and Leveling, both are 4 player dungeons done in the story (MSQ). The only difference is not being able to skip cutscenes.

However not skipping cutscenes is hardly ever proven useful, but a burden endured only for the leveling bonus. Most of the time this roulette will have 0 players who actually had not completed it on that character.

Honestly I'd love for them to remove it by whatever means, it just seems like something to endure for leveling as part of a routine rather than content of interest at all, all the renovations made just made them more boring, but they always were.
