Before I turn this into a full blown suggestion (not like anyone higher up is listening anyways), I wanted to speak with everyone about the matter of 5* rarities. I play this game regularly enough to have accumulated 81 5* orbs. But I'm not going to use them because 5* rads are super rare to heat just 1 5* gear. Heating shields? Fugetaboutit.
But what if we could brake down 5* orbs into stacks of smaller orbs like we do with heat crystals?
One part of me says no, it's supposed to force players to play the old levels at lowers depths to have a chance at orbs and appropriate heat crystals.
