Hello, I think it would be nice to add Tinkers' Construct or maybe Mekanism, because these are really nice and easy mods to use in a sort of skyblock-ish modpack.
Hey, We made the decision we would not add nods commonly used in skyblock so tinkers will not be added. Although if we have a need for Mekanism we might add it.
The packs credo is : Something fresh. Not the same "Hey lets make smeltery and uber weapon and tools first - because a smeltery on the moon is soooo much science." It would also break the complete balance, as would mekanism.
