I tinkered with RA against the computer. I beat the computer back to his homeworld then just built about six of the gateway thingies. For starters, it took a whole lot of resources to get to that point, and even more to build the gateways, but I finally got them going.
First thing I notice is that they don't just have ships start coming in, you have to pay for them each time, and they ain't cheap. Having six of the gateways is a waste because I can't afford to spend the money to "summon" on all of them. Next thing I notice is that the best fleet I see is maybe two heavy cruisers, a light carrier, and a frigate or two. The worst is maybe one light carrier or just a few frigates. The fleet composition varies widely and sometimes is complete crap.
After about thirty minutes of doing nothing but trying to put all my energy into RA (after it's up and running), I got a crap fleet. I spend the next thirty minutes spending the same money to build a fleet manually and I have a much better fleet. WTF?
I figure I have to be doing something wrong because there's no way spending all that cash to even get there still underperforms just building your fleet manually.
Can someone tell me how RA is supposed to work in the latest version of the game? I have entrenchment if that matters. I'd like some details as to what a typical summoned fleet looks like for you and how much it costs because I was spending more money to summon the fleet than the value of the fleet that was showing up. I'm not talking scuttle value, I'm talking the value to buy the ships from scratch. In my experience, RA is completely useless and a net loss in resources.
