Is it a good idea? Because if it won’t hurt my progression too much, I would very much like to. I’m still at that stage in the game where even the Common hybrids are useful, so I’ll certainly be able to use any hybrids I fuse.
If more hybrids are going to get Superhybrids in the future, hybrids that would otherwise not get me very far would remain useful for longer, maybe even into the endgame. If they don’t, I can always keep them for the sake of unlocking every creature in the game, and to admire their designs.
