I would have greatly preferred a research system based on time / quanta / resources rather than pay and wait, at least it pushes you to do things on the side to search for new ores etc, knowing of course that research unlocks others which cost much more expensive (and even more with the number of people in a clan, more recoverable resources, So more expensive but faster and it prevents the guys with X reroll to unlock everything), it allows to limit the craftable things (even if it means to add a system of duplication of schematic X quanta gives you Y schematic) At least I find it better and it pushes to gather and make tactical choices when unlocking crafts (limited to 2 or 3 simultaneous research)
