I myself spent 500 bloods on Leystone ore, prospected it all and crafted all the blue gems into their corresponding stat gem (Mastery, Haste, Vers, Crit) sold the other blue gems that aren't used in a Stat gem. Dunno what I am going to do with all the gem scraps/green gems. But so far I made a ton off of that alone.
What did you guys do?
