I don't like the idea of AI controled RA.
There is a good discussion in the beta forum about this. One idea there I'm fond of is that each gate would have, say, 20 ship points which it could spend on ships (probably have to also take these points from the players fleet points to prevent the infinitely sized army), the ships stay forever, and are replaced for free after dieing, after an appropriate waiting period.
Consider this: Vasari VS TEC.
Vasari get lvl 8 RA, and tec get that economic bonus that give them 10% of all resources spend everywhere by everyone. I bet tec can keep up with RA preaty well. You may have free ships forever, but tec now has free money forever, or maybe a plannet killing big a** gun.
What happens though, is Vasari focus on advancing in tech, and TEC just lets them, then all of a sudden TEC compalins, OH NOES, RA is too powerful. It should be powerful considering what I just spent on it. Now if TEC would take an military advantage and attack before RA is up and running, they could stop it easy enough. Or, if TEC would focus on some level 8 techs themselves, they would be much better off.
Problem is people think they should be able to withstand lvl 8 techs with a bunch of LRMs.
