I actually got a very well rolled Strongarm to drop naturally, I was pretty shocked.
I have been gambling for weapons lately as I need nothing else and it is disheartening. Too bad you can't gamble for both Sun Keeper and The Furnace in the same slot. It's annoying how tied you are to a good weapon as a Wizard.
Here is my t6 farming spec if anyone is interested:

I have been swapping between Storm Armor with Strongarm and Ice Armor with Warzechan. I like Strongarm better though for the BH + Molten Impact combo. With Leoric's, I basically have BH and Molten up anytime I run into a pack. Not sure if it's better than Mage Fist or Cindercoat yet, but I like having my cooldowns available in this build. Things can sometimes get dicey if you don't have a weak mob available for the gold drop, but you just have to plan accordingly.
Not sure if you're looking for advice since you linked it.. but, first of all, I would advice against gambling for a weapon, especially Furnace which is one of the most rare weapons in the game. It will take you A LOT of time and shards, and you might as well use the shards on other 5-shard-items because you WILL get those way faster.
You'd probably benefit more from replacing Storm Armor with Energy Armor (Prismatic Armor) and replace Glass Cannon with Blur (passive), and unless you really need to flee a lot, I suggest replacing Illusionist with Audacity. Not sure why you rerolled a secondary on your chest, but if you get a new one, you should consider rolling it into a skill damage.
Awesome Talons, btw!
If you want more out of it, you could try replacing Metero with Hydra (I mean, you already have Hydra dmg on your source AND shoulders, so it would be better).
If you get a great 2H, you need a RoRG for your 6P Firebird's, but whatever happens in the future.. this game is incredibly unpredictable and a very build-to-build situation.
