Here it is:
Make one type of orb and fire crystal, and require a certain amount for crafting/heating a piece of gear based on star level.
This will solve a lot of problems, and make every last orb and fire crystal count.
Wouldn't players farm easier levels and still make the same progress on higher level gear?
Well, not really, because enough orbs/crystals would be required so that it would take a long time to get the orbs and crystals from lower levels.

Actually, this could work. More of these things dropping in deeper levels...with a smaller number in shallow depths... yeah. And we'd stop having ridiculous piles of rarities we will almost certainly never use...(we get these piles doing areas that are more worth our time due to crown output). I'm more supportive of the idea for forge crystals. The forge disgusts me in on so many levels, there are better ways to "balance" free elevators economically, if that was even the main reason. But it would work for both orbs and crystals. Gosh. What a simple solution. With some fine tuning of the numbers, this would be a great balance between OOO's design and what players desire.
It's like a true recipe. There are many foodstuffs that take special amounts of special things (spices, etc). But many things require high temperatures to cook (baking, frying, whatever), water, etc. Rarities are these fundamental things to all the fancypants material combinations. Yes. Makes so much more sense to simplify rarities further.
