Harder ic2?

    Hello. I am making a modpack for 1.12 and I currently don't want to use Gregtech for 1.12.2. I have been trying to make the pack harder without GT but I am all out of ideas. If you have any ideas I would like the help.

    IC2 got a lot of predefined config into the mod options menu, the balance tab is very complete, you can change generators production or uu matter consumption.
