chest rarities
Well from what I can tell each tier of gear, ie rabbit is 1-10, deer is 11-20, has either two or three different sets of armour for each armour type. So if you get the cheap chest then you will only get the common armour, but with the expensive chest you can get the more rare armour.
hmm yeah but if you salvage the cheap stuff you can get slivers and crystals and craft the better one.
I tend to agree, the chests are a joke IMO. And I think you are better off buying the copper chests and salvaging them.
