I’m predicting that uniques will be able to be tempered. Also, thinking that they will make some general adjustment to how much an item can reroll on tempering, or a way to reset a “bricked” item.
For the record, I was mostly fine with the current tempering system, but it does seem like a resonable thing to adjust, as it is hard to argue that getting some garbage affixes on your 3 GA item with otherwise ideal stats feels bad.
They definitely are gonna temper around with tempering forsure. XD
I’m predicting there will be patch notes tomorrow. Some people will be happy, others won’t, and we’ll see even more posts flooding the forums.
Prepare yourselves my friends, if you haven’t done so already I highly recommend stocking up on 
Its going to be a wild ride tomorrow.
" We’re gonna temper your tempering so you can temper some more" ;D They’re gonna make shirt out of this just like Damage on Tuesdays. XD Im calling it now.
Bliz:“How do you like your steak sir?”
Me: “Tempered” LOL
Sorry Im having a field day with this. XD
doubt they will make uniques able to be tempered
Temper your expectations for the patch. Hah
I think some changes are likely, although I’m not expecting anything revolutionary. Just minor tweaks.
So, my predictions for funsies:
I don’t see them adding it to uniques in this patch, mostly because I feel like it’s something they may not want to mess with until they’ve iterated on tempering legendaries a bit more. It also seems like the sort of thing they’d like to save for a season feature if they do it.
I suspect we’ll see an increase to the roll limit. This is a fairly safe change, that doesn’t disrupt the current system but makes it just a bit more forgiving.
I’d like to see a no change option. (It feels terrible to me to have an item with a couple rolls left and feeling stuck with an option that’s sub-par but not useless out of fear I’ll roll the useless if I keep going.) But, I suspect they will be conservative with the changes in this patch, so while I’m not counting this one out, I don’t considering highly likely.
The change I’d really like to see would be for them to add in some new manuals that let you target a much smaller pool of affixes, but that have a much higher material cost. (Proportional to the number of options in the manual.) Give the players an option on how much they want to gamble. This seems very unlikely in this patch, but I can see them adding more manuals for seasons.
You will be able to reset an item’s temper limit with Platinum.
That likely won’t happen. That’d be far to meta changing to introduce mid season, it’d basically be giving the finger to everyone that struggled without that power step in the first half of the season.
At best they’ll make it easier to land the build that you would have wanted, but not introduce an entire level of power creep. If there’s any sort of introduction of power it’s usually through unintended bugs or effects.
Granted, they did introduce those class specific rings mid season 1 
But introducing a set of rings is probably more predictable than what opening the door to tempering uniques would cause.
Patch should be like:
“Temper retries changed to 4. Now stop crying about the limit, or else…”
I honestly dont see what they should change.
Game is in a perfect state, dont need patches anymore
Maybe Uniques wont be in this patch. But I think not being able to temper them is too much of a demerit to using them, to not change at some point.
Lock out items behind their fishy “RANDOM” algorithm is unacceptable.
I wouldn’t expect this until S5.
Also S5.
The best you can legitimately hope for is the Temper% made visible, and the ability to keep your current Temper.
They have stated that they know and are leaning on Legendaries being more powerful this season. That can definitely change but probably not and shouldn’t be this season – they’re to risky of a change to wide scale introduce that right now. They suck at balancing already as it is.
Then don’t balance. Make people have fun. Disable pvp until they feel it’s balanced.
Legendaries should be more powerful when looking at the affixes. Uniques should be useful because they do something very special that you want/need, even though the item appears weaker.
If most builds want to use 1-2 uniques, that would indicate a good balance.
Tempering uniques would be the worst possible change here. Uniques would no longer be uniques.
i predict we get vaults to farm gold, since every season they add something from the previus one, vault being the favorite thing about season 3.
They definitely should though, it already felt bad enough losing an aspect for a unique with no customization options but thats even worse now with tempering. A lot of uniques are still trash and underpowered too.
