BTW, if one is already in the update mood, one could also pimp some U.Class planets.
The good U.Classes are U.large and U.spaz. The rest basically sucks.
Except restarted empires, nobody is really happy finding a U.Rich, not even strip-miners, since the speed of harvesting the ore too low. U.Eden is a short cannon fodder for plundering empires, and the U.fert is only good for people, who either can not calculate, that a good C1 makes more food, or for people, who have way to much gordos.
Why not make the latter U's more powerful, giving them more ore, or more land respectively, that it would be nearly worth to keep em, of course not as good that they become better than an average C2.
And increase the rate of X.U, thaey are fun ,-)
