hey guys I've spent a month figuring this out well this is what I got and it always works for me I'm rich in conquer because I kept using this trick to get sockets and selling it, well heres the trick it is mainly on the kills you get
weapon socket : 4000-5000 kills
armor: 7000-8000kills
necky/rings/bag/brace/boot=9000+ kills
I can promise you that this will work with using 1 met after u get the required amount of kills it worked really well for me and i hope it'll work for you too
