Main Scenario Restriction Bloodstorm - Very Very Bad idea.

No, it fact, it is hurting the game. If you give options to skip a whole bunch of content, the Dev-Team won't make the same efforts to design them with lore and stories. And you'll have more and more complains about the lack of content. When a game is young, having little content is understandable. But, if a new player comes on the 4th expansion, and burn anything relevant in a month, of course he'll be pissed by having nothing else to do than dumb grinding. We've said before that the MSQ is relevant on itself, that first time run in dungeons are relevant. Adding a skip potion is an official way of saying "No, it is not relevant anymore".

In fact, it's like adding powerful items in the cash-shop. It would only be an option for some people, after all, and wouldn't change what you like in the game. But you bet it would destroy the community and the game.

That'd be on the player who decided to skip the story's fault, and not only that, the dev team already said it was a whole game's worth of content in the expansion so they're will be plenty of content so they'll get their money's worth. Also as I said before,

Some players may just go back to experience them after they had plenty of fun with the expansion.

If they feel that the content is low, then all they have to do is make an alt on the same server and experience the earlier content while they wait for new content. So yeah, its not hurting the game.
