i actually got really deap into mystcraft what struck me odd about it is that it dosent fit the theme of the rest of the mods, it is the only mod that is "magic" the other mods are realist in a way but mystcraft dosent fit this theme, it also is very stressful on the severs because it is spawning a new world in your world most servers have it disabled i dont even think you can make a server with it i think it is best for the mod if it is removed
i am pretty sure mekanism was updated so that it is possible to make refine steel without refine steel
