In Tekkit there are 67 mods with 18 pages showing in nei , and this is after all the microblocks were hidden from NEI. Do you really think that there is only a linear power progression available? There are a gazillion options. You just need to explore a bit. IC2 is gone because IC2 is dead. Keeping it in isn't even an option. We understand why you are crying about IC2 being gone, but it really is kind of irrelevant why. IC2 is dead. Its so dead its starting to stink. Vultures are gathering. Dead.
However, there are options, many many options. They are not the same options as IC2 had, but there are plenty there.
Not quite sure on what you are suggesting though, it appears to be a system to force a linear progression of power? Which is what you were complaining about?
