But in all seriousness, you just run old server images. It's not hard to make an EE2 server and if all you have is EE2 it will work fine. Minefold still maintains tekkit classic servers if you wanna go back there with a free-to-play 1 button server setup. I have one I visit every now and then!
Personally, I think EE2 was a very fun mod. The big problem with EE2 is that it was poorly balanced with IC2 and players got resentful of how much more effective EE2 stuff was. But if you played EE2 by itself and ignored everything else, it was great. It had a progression that worked well with vanilla minecraft and even buildcraft.
It's too bad otherwise smart people are so busy hating on this mod as a sort of me-too-ism. EE2 was not creative mode, but it was a mode that focused heavily on giving you the power to do amazing builds.
