Main Scenario Restriction Bloodstorm - Very Very Bad idea.

How is the story quest at all related to that? You get more experienced tanks in later dungeons because... they've had more time to learn their class in the earlier dungeons. That has nothing to do with the story quests at all. They never teach you anything but how to be an errand boy/girl and occasionally how to hit some mobs on your own.

All dungeons are MSQ required, which forces people to wise up to their jobs faster. As a result? Better parties. Furthermore, every dungeon is explained in the MSQ leading up to them and most are pertinent to the MSQ over all.
