Hi guys. I've been having difficulty with this and would greatly appreciate some help. Could someone please tell me the full process? I've heard you get prompted after you spend all of your skill points, but how do you use those couple that aren't enough to get a full skill? Thanks.
isn't upgrading your ship like getting a new one, customizing it?
No. Ships have tiers. The higher the tier the stronger the ship. Lieutenant ships are tier 1. Captain ships are tier 4. You cannot make a Lieutenant ship be just as strong as a Captain ship. That doesn't mean you can't use a tier 1 ship at the rank of Captain, but it will be harder to win with. Also, each tier doesn't have the same kind of ships.
