Not 100 percent sure if this will happen but

Yeah... no thanks.

All they need to do is:
- Make the boxes farmable again, but at a much lower rate (10-20 an hour with no drop multipliers would be reasonable I think).
- Bring Alien Cubes back and get rid of this Gachapon and Fusion only garbage.
- Release S Rank Nebulites.

I don't think a second socket is necessary since you can get 20-30% main stat with just 2%s. Think what that would be if 4-6%s become more common.

Couldn't have said this more perfectly.

The boxes would still drop at a low rate and all people would have to do is try and collect some B's and A's and just work on cubing those. Gachapon and fusion was like the mark of death for nebulites. Even now in windia people buy hordes of garbage B rank nebs to fuse them into higher ranked ones that actually count. This in addition with not much nebs resulting from gach lately means extinction is inevitable unless something is done and THIS is that something.
