so i know the repetitiveness of it bothers some people, I too wish it was more like nyzul which i thought was pretty amazing.

But the only thing that really truly bothers me about it is the silver chest randomness issue.

My first couple groups in there we got enough chests to just progress through the place 1-50

and then we decided to bring a friend along and had to do 1-20 four times and then 1-30 three more times just to get enough upgrades on her to progress through the place.
it really kills the enjoyment when it decides to give a group 2 upgrade chests over the course of 20 floors and then "whelp we decided to screw you over, go back to the beginning and do it again"
