So the trouble I'm having is my friends are all engineering students and they love a modpack that is grinding and brain thinking, we've played TEKKIT, THE B TEAM & BIGDIG but they are getting bored of them all and want something bigger and better, I run a server for all of us so, size of modpack doesn't matter. They love Thermal Expansion and Tinkers Construct, just wondering if anyone could suggest any modpacks that would be suitable for my dilemma. Thanks!
Enigmatica 2 Expert Skyblock fits this criteria. It's the most fun challenging grinding modpack I've played in quite a while. I played it solo but it would be SO much more fun as a team. Automate everything from the start and you'll be golden and you'll have fun doing it.
