The shrines' bonus does not stack with the system robotoid factories, but it does with the planetary ones, since the shrines uses the same ability as the system robotoid factories.
High maintenance reduction can be an exploit as well; I guess I'm surprised it's not on that list as combined with crystalline it can lead to practically maintenance free ships...
The aggressiveness and defensiveness affect your chance to hit and be hit, and they are quite powerful traits. Consider a race with 130% defensiveness going up against a race with 100% defensiveness. At range 1 there is a 90% chance to hit (100% base to-hit minus 10% for the distance). However, the race with 130% defensiveness will only get hit 60% of the time, or 2/3 as often, as the race with 100% defensiveness! The discrepancy gets worse as you go out to farther ranges, say range 7, where the to-hit chance is 30%; then the 130% defensiveness race would never get hit at all were it not for the game's 1% minimum to-hit chance. That's a 30 to 1 ratio of hit chances!
