Ignoring legal concerns, I for one don't like the hundreds of recipes, even vanilla DOS2's recipe was too much for me. Adding more makese the gameplay too much of a clutter, and a lot of the game becomes less working with the tools you have, and more memorizing a list of tools you can have once you farmed enough materials. That, and keeping track of all those materials.
The freedom of how you can solve problems in DOS2 is what I love most about it, and too precise tools will ruin that. If you have a tool for everything, you no longer need to try to cobble together a plan with multiple tools, you just pick the one thing that the designer deemed correct. When you have a thing for any situations, your choice is practically taken away, because why make Rube Goldberg strategy when you have that one laser gun that only works on this specific boss???
inb4, no DON'T make a mod with a laser gun.
