Why does (almost) every single MMO expansion have to be some world-threatening major event (usually brought on by a ooky spooky cult)?

Why can't we have some lower stakes shit like
>A murder happened in Hammerfell and now we need to help the local nobles solve it.
>The orc clans residing on Balor are at war and we need to help bring peace between them.
>We were hired to basically serve as the "Smiling Friends" for some Hobbit leader north of the Shire.
>Two archeology groups are racing to excavate some old Rataka ruins on Kashyyyk, pick one to help

out of touch execs think plot points have to one-up the previous thing ad-infinitum

Because in their eyes thats low level content

To make paypigs and self-insert faggots and think they're relevant and wold-changing, similar to the gachashit cheap plots.
