Easily fixed with a way to reset Tempering durability somehow. Amazingly, Blizzard still have not learnt their lessons when it comes to stuff like this.
RNG is only “fun” when it’s fair and used sparingly. Tempering has become an integral part of the game now, why give us only 5 chances and allow us to brick amazing items like 3x greater affix items?
Give us a way to get good tempers eventually, even if it’s costly.
