I would suggest making RER work with this modpack as there is so many different ores that are required for advancement through different modpacks and it is extremely hard to find where to find those ores, For example to get zinc you must run Sphaelarite ore through an electralizer and it says that Sphaelerite or can be found in the Nether at nearly every value online, but having searched the nether extensively I can almost say it does not spawn there.
