I think the msq would be more fun if you had more content that wasn't either "find this NPC", "fetch a NPC a Apple" ect.
Needs honestly more Dungeons and trials, I know with the amount of MSQ you did in-between the dungeons/trials and even solo duties, just wasn't enough compared to all the filler content in-between the MSQ.

I doubt we will get more dungeons/trials in 7.0 my expectation is the standard 6 Story ones, I can imagine if it was like 9 or something to break up those slower moments in the story it could actually make the msq more fun and interesting to play through.
