Why does the Moogle Treasure Trove event give you incompletable weekly challenges?

I had assumed mogtome event duties scale according to your progression like Khloe does, but I guess not???

They never did. People keep complaining, and SE keeps ignoring the complaints.

Personally I think the duties should at least be scaled to your level. So when you're 90, a 90 raid duty would be ok for me - even if I haven't opened access to that particular raid yet.
But a level 90 duty for a level 50 char? That's just dumb. Or lazy. Or most probably both.

And to add insult to injury: my main char who has access to most parts of the game - always gets Dzemael or Cutter's Cry. The level 90 duties seem to be reserved for my chars that cannot possibly do them :/
