So my gear is pretty stuck at this point until I get The Furnace (or a really good Sun Keeper):

I don't think I can progress past gr35 with Maximus as rift guardians simply have too much hp and there is too much RNG for Maximus spawning.
Outside of The Furnace or Sun Keeper, I've been toying with the idea of using a Mirrorball build again with upgrading to a super high Simplicity's Strength gem. Would this be better than the Toxin gem and a high 2hr weapon (taking advantage of weapon dmg)?
Maximus is nice for clearing out trash because it seems to spawn more consistently with a lot of mobs around. With a Mirrorball build though, you could get the Maximus fire chain crits from your MM more reliably. I guess the problem would be figuring out what slot to give up in the skill department, which would be Hydra. You would then lose out on Hydra damage + fire chain dmg, so that would have to be a pretty huge net gain.
Simplicity's Strength scales pretty well in terms of gem upgrading though (0.5% each upgrade), so it seems easier to catch up in damage.
This is probably a terrible idea, just theorycrafting for something to shoot for since I won't be seeing The Furnace anytime soon
. I feel terrible wasting Kadala shards on it, especially since Sun Keeper and Furnace are in different groups. Would be nice to have something to shoot for instead of just that one singular item. I am tempted to try and get a perfectly rolled Strongarm Bracers so that I could re-roll a secondary into 6% melee reduction. The physical resistance on mine might be just as good, however.
As a side note, I am also tempted to upgrade Moratorium too so that you can get a pretty high duration going. Might be able to substitute out String of Ears for something like Witching Hour once you can stagger the damage duration.
