there is also skills in engineering and other groups that increase CAP, CAP regen, decrease module CAP use.
so look at what skills you have, what ships you’re flying and the fits you’re using, and the combo of what the others have already post and your skills will help fit CAP issues.
also look at your fit and simulate it with active modules you’d normally have running to see where your CAP issues are, never have ever module active as 9 out of 10 times you’ll never be in that mode.
