I get so tired of this argument. the simple fact is it does cost more. I can get it for the same amount using the enchanting system. It cost the same in reg FTB mod packs. There is no balance reason to have it cost more period. It isn't a ground breaking modifer i mean what else are you keep silk touch around for in Skyblock maps for. there are no ore in most cases. and after you get a harvester going you don't even need the thing which make the enchant next to worthless. This new change for skyblock map just ensures that no one will use it. you already have to unlock cobble and then cobble gen. After that spend a 15-20 minutes with your hammer gaining the gravel only to have to get 12 stacks and pray for 9 to drop. It doesn't even make since for 9 gems to make 1 gem. You would think i was trying to make a MFSU.
I'm curious, is there some special trick to enchanting something with silk touch?
