5k is generous considering the effort involved in sending them out on missions takes all of 2 seconds.

Even so, mine occasionally bring back items worth 50~80k (usually in the form of rare furniture), and more often than I expected: dyes - if I'm very lucky, black and white.

But yea, most of the time you're going to get augmented poetic gear and a merlthor goby.

It's free gacha.
