Design Suggestion for Subquests

I would really appreciate if future expansions avoided situations wherein the MSQ opens up a new map, and also additional subquests in the old one. I find those subquests increasingly frustrating to do, and I've begun spamming through the dialogue because I'm torn between wrapping up loose ends on the old map and proceeding to a new one.

And I know, an obvious solution would be to simply leave the subquests for later, but I don't think I'm alone in having a strong preference for 'clearing' a map before progressing on the MSQ. I've also yet to see many of these 'post-MSQ' subquest unlocks depend in any way upon the MSQ being done, so they could easily have been shifted so they unlock earlier.

Just my two cents anyway. Thoughts from others?

I think it's fine. When you want to level another class to 70, side quests are a good break from potd, pvp, and FATE grinding.
