Shields - No one anywhere EVER in d3 who knows what they are doing uses a shield. Unless they are trying out a funky echoing fury + shield chakram build at least. These will never be good, and if it is good, it will never sell, because shields are absolutely useless.
Chance of being good - 0
Pick ilvl 63s only, pvp will come one day. Then they'll be usefull for a change.
Sources and Fetishes - Need a complete perfect roll, and there are many affordable alternatives even if you roll perfectly on either one. Avoid
Chance of being good - 2/10
WD will go for the frog if they know what they're doing... hard to compete with 20 yard pick up radius.. I m sure the other legendary/set mojos are concidered useable.
Wizards will go triumvirate for archon, chantodo's for perma freeze.
Occulus also give nice teleport option... frankly you're wasting your time picking these up.
Pants and Chest Armor These rare drops have the potential to roll good enough that they will sell, pick these up.
Yeeah... maybe. MAYBE. Inna's pants are tough competition for farming speed high dps output for barbs, perma freeze, dh and monks. Depth diggers for high classic stats. (you get everything there and more (MF))
Or you can go Blackthorn pants for life on hit bonus which is nice.
Yes some people will go for rares at times, but mostly cause they're gonna be cheaper.
Pretty much concur with the rest. Oh and do concider picking slayers as well they can be awesome off hands although... chances are really low.
