I completely chipped out 4 times and I can say is a bad idea. I would rather pause
EU than chip out again.
If you still want to chip out, better chip out everything, except two skills: LWT & Anatomy.
And something else, I think you maybe have some misunderstanding of the skillsystem:
- "some levels in activities related to weapons" - those most probably mean your laser weapon engineer prostanding. If you never crafted, that prostanding is generated by LWT and engineering (from mining).
For example, once you sell your dexterity skill, that would bring down a bunch of prostanding, like paramedic or ranged laser damage. So you can't sell the paramedic prostanding from 11 to 5 directly, but you can sell enough skills which to bring down that prostanding, among others.
Sry if I misunderstood your words.
