I tried using my warrior monk with a running build and started to hunt for shiverpeak chests, because I wanted to try out using those keys that I can buy at the merchants. However, I found that it's very easy to run to chests and have a very good shot at getting a gold item. I already unlocked 4 different weapon parts and 5 runes, and salvaged some very useful parts. Seems quite abusive to me (unless questing in Sorrows Furnace can give much better stuff, haven't got that far yet). It's easy to farm enough gold to buy these keys and get gold items (and farming may result in gold items too), so farming may be back.
I stopped running becaues I want to check out the new content, but so far this seems to be the best way of getting gold items.

) but one was a max-dmg gold axe that unlocked two mods for me. If I can get a reward like that one out of every 3 or 4 chests... that's an easy decision for me. No more playing the market, just buy keys and let the unlocks roll.
