There is an assumption being made by some that if they complain enough they’ll get it so they can have more rerolls or resets or some other means of taking their current item and rolling until it’s perfect.
This is very much not likely to happen. Just as masterworking in the PTR wasn’t really about “failing” (it was cost obfuscation), tempering isn’t a crafting system, it’s part of the drop system. Tempering is the compromise that drastically improves the odds for the player from needing to drop 5 affixes from very big pools to 3 affixes from relatively small pools, and 2 affixes from very small player chosen pools.
When they “fixed” masterworking, did they just drop the idea of high costs? No, they just made them more transparent. It’s quite possible the player was better off “failing” in the system we saw in PTR, than the costs we see now with masterworking.
Tempering is the same way, it’s not likely to become the perfect item paradise it’s detractors think. The devs have a vision for the economy of this game, and that includes very rare, borderline impossible to obtain gear. While they’ve ceded ground here and there, particularly with uber uniques, they’ve remained steadfast, even in the new itemization system, that some gear have the potential to be very, very strong but exceedingly rare.
The problem is, the players disagree. They may say they want such gear in the game, but when they see the possibility of a perfect 3 greater affix drop, they assume they’re entitled to it becoming a perfect 5 affix tempered item. That’s simply not how this is designed, and unless the devs radically change course, any change to tempering is not likely to result in that.
I fully expect, at some point, a change to tempering because the feedback against the current idea has been so large. It shouldn’t be, as every player here has dealt with nearly perfect items dropping before, and that’s all this really is. But there’s admittedly a psychological effect here in the player playing a bigger role in the final outcome that just doesn’t seem to allow many players to accept this system. So while I think it will change, I warn everyone that you may like the new system even less.
