i am totally for stealth tech, and remember stealth also has variety. You got "Predator" style cloaking, to make you invisible. There are also stealth by jamming a signal to not appear on radar, or other methods to not appear on radars. While your ship may not be invisible, it can be invisible to detection instruments. Also decoy mechanism, which isn't entirely stealth but it is in the stealth/covert mind state. Dummy ships, fake signals, miss direction of signals to lead people away.
Im hoping for stealth tech a lot of areas it can be added to as the game progresses in time.
