I just hope some guides will be made soon. I'm relatively new to Technic in general - only started using Tekkit Lite a few weeks ago - and I freely admit that I relied on IC2 a lolt. Now that it's gone, I'm at a bit of a loss of what to do in starting a new world. I'm no genius, and figuring things out for myself only gets me so far. Even with a guide to follow, I had to restart one of my worlds after screwing up my first base (In Tekkit Lite, that is).
So yeah. I'm willing to learn and use the new pack, although I hope it won't be all on my own. There's a LOT to absorb, especially for a non Technic-vet.
