Build will get extra dps out of spirit generator and blazing wraith while staying alive pretty easily going through cooldowns and using blind effectively. Keeping winds up and you'll generate enough spirit during fights for whatever you need. Resolve could be swapped out for a damage buff if you choose.
On hell difficulty I do the kill azmodan quest, running to him you usually find 1-3 rare/elite mob spawns, save all the chest, once you make it to him, teleport to town go back to the core of arreat and go backwards through the spire until you get 5 valor. Then you can go kill Azmodan, getting the chest along the way, usually get at least 2 rares and another 6-8 blues. Not counting rares you might find off elite mobs. When you kill Azmodan you get 2500 gold also and can finish the quest to get another 2500.
It takes all of 20 mins to do this, depending on which elites you get and even if you don't get the items you want you'll get enough gold to buy an upgrade in a short amount of time.
Hope this helps.
