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

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 :/

What's even more silly is that there's a good chance highlevel characters don't need the rewards. I have everything save the mogtomes exclusive on my high level characters but could use the rewards on some newer characters that have no yet reached lvl 80 (it seems to be EW normal raids and Shadowbringers' alliance raids this time). I couldn't care less about an earring that is barely visible in game and just uses space in my dressing.

I also dislike the fact that you can't even know which raid it is in the series (i.e. the first one, the 5th, the 12th?). It happened with a past mogtome event where the Omega raids were the normal raids used to mogtome: my character had just reached the point where I could unlock them but there was no way to know how far in the series it was as it can take a while to do them all due to having to wait in queue and I wasn't at a level where I could solo. I can't do them all in a week due to RL.
