Some help please.

Can you please tell me, why you have made many crafting skills (like Augmentation) with many sub-skills instead of using just 2 to 3 skills in the skill tree.
To explain: the Weapon Augmentation has
3 Decompose skills, 3 extract & 3 undo… the hole skill tree could be only 3 skills and let the system decide the result.
This system is used in all (many) crafting skills you have. Why is that? Does it fulfill a purpose?

Thank you.

(Note: I love the game. I just don’t understand some inefficient ways of doing things…)
