I remember in a demonstration video we where told that research results would be random. We would see what me MIGHT get, but the result would be random. I thought this to be VERY interesting, and give an exciting game-play (especially online). No longer would players have a specific "building plan", and we would have to use our wits.
But so far everything is set in stone. I research, and then can freely select which one I want. No random result at all.
Did they decide to drop the random research thing? Can we expect it to make an appearance in future patches?
