The RNG needs to change. It's seems so lopsided. I'm currently 22/15. Just went through floors 21-30 again. I couldn't upgrade my arms, but my armor was eligible about 2-3 floors in. We got 5-6 upgrades-- all arms, no a single armor upgrade.

When will companies learn that RNG is just a frustrating mechanic that makes things extremely easy for some and ridiculous hard from others? Someone should be able to get their weapon in 2 runs while someone else has to struggle through a dozen of them due to bad luck.
