As much as ill like to make it just require ingots, i cant... because many players would just install veinminer and make thousands of galgadorian easily.....
I think we need to ditch the Galgador thing. Save the Galgadorian metal for recipes for machines and armors you think are op but don't want to remove from the game. this pack needs progression so how about this.
Early game right now you have two mods with their own materials, Flaxbeard's brass and gold plated iron, and Botania's steels. your next tech level seems to be pneumaticraft and ender io, so maybe you have to use manasteel for your first tnt set of compressed iron, and maybe the capacitors require elementium and the ender io machine block takes brass or bronze.
Next level is Mechanism, so the steel machine blocks now require Ender io alloys, like vibrant alloy or dark steel. and some recipes have a pneumaticcraft plastic component. (vibrant alloy requires redstone, glowstone, and ender pearls)
Next level is Galactricraft, and now you have to use the mekanism atomic alloys to make the machine blocks.
This progression limits the ability to just use plain ingots but won't require quite as intense a grind and will force a progression through each mod.
Again, don't keep trying to satisfy people with different galgador recipes and insane amounts of galgador. Also, since you are playing with recipes anyway throw in the occasional block of some of the metals like tin that aren't getting used for anything. and go ahead and make us compress them in anvils or whatever other arcane things you want. If I wasn't farming meteors and spires for days trying to get a bajillion emeralds (1 in 4 spires and only 4 emeralds per spire) I wouldn't have such large stockpiles of the other ores. Save galgador for steve's carts and the blocks you don't like because they are "cheaty" or "op"
The way the pack is now you have all these metals and resources but the only things that you are actually making use of are iron, gold and emeralds, everything else is mob drops or a block less useful and more plentiful than dirt (hardened clay)
