Huh. Not my experience. Still material starved at 65.
not that serious, just salvage when you need it and sell when you need it, its all RNG drops.
Sell weapons salvage armors is a good tip too, and on the end everything depends on what you need the most, a full inventory of rares is at least 400k gold (level 60).Legendaries should be salvaged as you will need the materials, but sometimes it's worth to sell them too for 35k or more, using the same weapon/armor logic above.
This and almost all of the information on this website really only address normal mode. Hardcore is the only way to play in my opinion, but requires very different end game goals since surviving is the #1 thing.Not upgrading your gear can be bad, especially early in the game while you have so few talents to deal with things.
once your into rare gear, vend all white and blues and shard all yellow gear except upgrades where you want to apply a legendary power.
