You read it right, if you have been following the news, testificates will actually be useful in the game with Trading, so why not use that with IC2?
Let's remove the Einstein title off steve and remove his omnipotent recipe knowledge so he actually have to look how something its made in the first place before doing it?
You could add a "Researcher" Testificate who sell plans of how to build stuff like generators and the like, steve just need to buy one of these plans, right click it and boom he can make whatever was in the plan. (thats just a little example of how it could be)
