A word to the wise who will listen to the wisdom of the Eldar. When it comes to loot crates if you buy the 1k crates there are 19 of them total. Do this first it will give some weapon damages and some other items such as compensators, stabilizers and general small upgrades. Next up go for the 5k boxes, and so on and so forth... Now I know your going to ask. "But Asheru why should we do this?" Its simple if you are limiting your chances of getting the lower cost items in the larger boxes. Next I know you are going to ask... "But Asheru how are you sure this works this way?" Well to be honest I do not know for 100% but I do know as I have bought almost 20 or so 5k boxes right now and I have not run into any duplicates or lower tier items so far. Its it a sure fire thing? No idea but so far it seems to be working for me. Why not try it out what the worst that can happen you might get unlucky and get a duplicate later on but better that than going for a 30k box and finding one of the 1k box items that you are forced to accept rather than it being something you already have and at least you will get a partial refund.
