No it's not ridiculous. Limbus is not fun enough to qualify as new content to do in your free time.
Sorry you don't like it.

I don't really mind it, and that's even considering how slowly I can do it by myself without multibxing. But I also don't care all that much for the stuff that got added after the first iteration. I've got plenty left to do personally given that I can't always do certain contents.

While it is perhaps disappointing that these rewards aren't more attractive it doesn't really affect me that much since I was unlikely to want any attainable weapons SE could possibly come up with (as a SMN, GEO, or to a lesser extent PUP). I guess you can't be disappointed if your expectations are not realistically meetable.
