These weapons seriously need some damage nerfs. Because some guns like SMGs use pistol rounds so they should be on to par with pistols a bit, and the assault rifles, 30 damage is a bit too high for any weapon. Just look how balanced HK weapons are.
I'm not too sure about the name. I clicked on this topic expecting magic spells, or swords, or something like that. Something about HearthCraft sounds like its a medieval fantasy pack, not guns. I don't know, just my opinion.
