What's the secret to making Jae good? Cold Trader's Acumen is a strong talent and of course officer is a strong class, but she does by far the least damage in the party (even behind pasqal who is full support strategist) and I'm already an officer and my abilities are a lot more impactful than hers (higher Fel and more focused talent selection). She's not even the best skillmonkey either, Pasqal still has her beat on the important ones like Logic and Tech Use, and other people cover Athletics, Demolition, and the various Lores. She legitimately is not better than anyone at anything, and she's not even a jack of all trades either since half of them cover several things too. And she has the lowest damage by far.

I gave her dual pistols but that was bad, I gave her a sniper and that was bad, I gave her a shield+melee+pistol and that was bad. I also gave her a dot build with the dual toxin pistols but she was worse at that than any of the archmilitants doing the same the same thing. She legit has no real home from what I can tell. She's a worse officer than pure officer, she's a worse damage dealer than any actual combat class, and she's a worse skillmonkey than the tech priest.
