Aurora is a pain to use. I need to max out flux stats (more so now that its flux stats were nerfed in 0.9a) and use short-ranged weapons. Great for bullying weak ships, but not so great against a tough fight. If I want to use missiles (sabots), then I cannot pass it off to AI (if I suddenly want to switch and chain my Afflictors in mid-battle) because AI is not competent enough with them. Moot when finding Aurora is hard, and by the time I get it, I have a capital or Doom already. I suppose I could use it for beam spam, but I do not need Aurora for that.
Combat Endurance is nice, but I do not have skill enough points left to get that all the way up to 3. Also, 3 is not much use if I swap from my flagship to other ship without an officer. (Late game, I often swapped from capital to a chain of Reaper Afflictors before battle.) Plus, if I am really desperate, I get more Officer Management instead (which is also a chopping block skill with a skill point crunch) and steal one of the extra officer's ships for 100% CR. Admittedly, I would rather get CE3 myself than constantly swap a ship to get the same benefit and more officers, but if I wanted to do min-max cheese, more Officer Management is better than Combat Endurance for the purpose of getting max CR from another ship, plus getting more officers.
I really like the perk from Damage Control 2 (and want to get 3 too for less hull damage), but it is not as useful as campaign benefits of babysitter mitigation skills. It really pained me to give that up for Navigation or Planetary Operations.
I really want to have enough skills to match level 20 officers, but unless I want to completely ignore Industry and abuse alpha cores (and the Pather cell bug), or forsake vital fleet skills like Loadout Design, Fighter Doctrine, or some Officer Management, I see no way to do it and still have an enjoyable experience with colonies without so much aggravation with harsh limits and constant babysitting.
The industry limits and harsher colony demands means Industry colony skills are must-have without cores. But, with the bugs, slap-on-the-wrist punishments (sticky jealous alphas, money-grubbing inspectors) that are easily circumvented, and steady alpha drops from a stream of massive Ordos fights, alpha core abuse is clearly king in this release.
@ intrinsic_parity: Helmsmanship is one of the earlier combat skills I get. Many ships are too slow without those perks even with doubled game speed of 2f. (I wished Starsector could handle 3f speed flawlessly.)
