I've been playing quite a lot of Sins in past couple weeks. I preordered the Diplomacy xpac but I haven't tried the beta. I've been playing the latest version of Entrenchment. I've played TEC exclusively and run into these annoying (not game breaking) things:

tec: Scout sensor rank 2, what does it do? Rank 2's tooltip is exactly the same as rank 1's.

for killing missions, capitol ships and other high value targets count for as much as light frigates and other low value targets, but I expect them to count for more

Friendly AI gives me missions that don't at all help its offensive or defensive position.

I hope my notes help a dev make the game better!
