Looking for Advice on Race Design

Do this:

Environmental Resistance: 81%
Reproduction: 103%
Happiness: 110%

You will get a few hundred extra points, and the only effect on your empire will be slightly increased happiness. Environmental Resistance affects the rate of reproduction and the happiness level, although in reduced amounts.

Cunning at 120% may be a bit of over kill. Generally, I encounter one of 2 situations with intel wars.
1) One empire is really far ahead of the other (as in 10x or so intel), and is able to pull off several successful missions per turn.
2) Both sides have large levels of intel and are thus capable of fending off all intel attacks.

Defensiveness at 80% will lead to situations were the enemy can go at max range and still have a good chance of hitting you, where as you can't really hit them.

Don't under-estimate trade. In PBW games, most players will have a lot of T&R Treaties. This could lead to a big advantage against you in games with lots of players.
