For TiC, I've limited the tool station to being craftable from steel. The ball of moss has had it's recipe changed so something more expensive & "awkward". I've changed vanilla wood and stone tools to flint and crude bronze, and the TiC Smeltry block recipe changed requiring a component you need to craft from materials that can only be mined with Crude Bronze.
So getting starting with TiC now needs around 8-16 ingots of tin+copper in addition to all the clay/sand/gravel/furance fuel. In my modpack, that's a lot of ore to gather and to survive obtaining early game.
A lot of time people say things are easy (in a lot of mods), but, really they are easy because ore gen is so common, it's too easy to find resources, so you can steamroll your progress quickly. *Shameless self advertising* that's something which I think I've addressed quite nicely with my Omega Dawn pack, ores are still "common" but they are mostly poor ores, so you have more mining to do, and more smelting (which means more energy requirements).
