Requiring DNA for biomods and better tech for avoiding creatures for more aggressive creatures AI

Biomods feel almost too passive. It needs to feel more like you need them. It would be insane if players had to scan a dangerous leviathon, than on top of that get DNA from something it drops than have it to edit your genes in the biobed. People would be talking about the challenge like crazy since you generally try to avoid them. People always talk about how they want in hardcore the more difficult challenge. You can satisfy both for the new player and advanced by enabling more aggressive smaller creatures but better biomods and tech to deal with them. So people don’t complain about excessively annoying creatures and hardcore players are kept very busy. Not to mention the excitement of getting a new vehicle module, tech or biomod. After all the game intro was all about the need to wait DNA.
