The true point is about missions. Having to check several USS which is a tedious time consuming task every time is not exactly optimal.
I said it earlier and i just can repeat: Missions is THE game element that can make the game attractive for the average player. It can make the difference between a game for fans (<80% rating) or for everyone (>80% rating).
this! I often catch myself alt-tabbing browsing reddit to wait for the next USS to spawn. Most boring thing ever. If i get a "search this pirate" mission, I want an engaing task not checking out 5 USS for an npc who points me to 5 more USS.
