You are cutting too many fleetwides.
15 Leadership: 3 base, 3 officers, 3 logistics (+15% CR is 5% buff to all stats), 3 maneuvers, 3 fighters
10 Tech: 3 base, 1 EW, 3 Loadout, 3 Navigation (the only out-of-combat skill I pick)
3 for base combat.
Which leaves 24 for personal skills, 27 if you religiously take only in-combat skills. Well, I guess we are slightly superior to officers after max level was bumped to 50.
I changed my mind, play vanilla and i see what i need, so thise skills are all what you need, no deends more. 10 personal skills.
I agree that Navigation is too cool skill, -25% fuel usage, +1 burn speed (-2 tugs, less fuel usage and supply cost, +2 fleet slots!), terrain penalty, and that Transverse Jump skill, okey.
And officers, i do not have problems with their limit. For battle field we have at least 200 deploy, so, it is 2 paragons, 1 astral, 1 aurora, and one more aurora for changing that first while it is out of peak performence limit, or add it in battle if you have more than 40% deployment. So, we have 5 ships, 1 for player piloting, and 4 for officers by that limit, so we do not need those officers.
10 personal skills, i am playing vanilla try it all, firs try, then talk)
