Allow MSQ Fast Track To Latest Expansion

[Berethos]

An abridged version is an interesting idea (though a careful look at the story there does reveal that trimming it is harder than it first appears) but it's not as feasible from the development side - eventually they'd need to do abridged versions of each expansion as the game gets older and the story gets longer and might reach the point where even the abridged version is too long for new players, especially if it remains required.

Things like that take dev time - rewriting for clarity in multiple languages, testing quest triggers, developing the systems for two versions if said current system doesn't easily allow it (assuming it would work at all currently), and that will inevitably begin to cut into dev time for future content.

Ungating it from content unlocks but leaving it intact and requiring one to go through it if they want to experience the story is ultimately the more elegant solution.
