Sorry might be a stupid question, but what should you take as the 6th skill for my 140 crew. I can take:

Commander: Firefighting, Mentor, Sound Detection, Jack of All Trades, Eagle Eye, Call for Vengeance, Signal Boosting, Relaying

Gunner: FF, Designated Target, Armorer

Driver: FF, Controlled Impact, Preventative Maintenance, Clutch Braking

Loader: FF, Adrenaline Rush

I am asking because I didn’t have the need for a 6th skill yet and the skill4ltu index only goes to the 5th. Thanks for your help 🙂
