Having bonus stats is not a good thing, as you may think.

I do not think it's a good thing either. I liked reforging back then. But then players had to go to reforger and change stats before even equipping it in raid. And sim what stats they should change. And people cried about it. So Blizzard took this ability away.

Nowadays I like corruptions. It's a a hugely successful thing to make your hardcore audience go do content outside of 15-25 keys and mythic raids. It's a hugely successful thing to change players' perception of gear. And sometimes it even changes playstyle, like melees looking into walls in m+ to not pull additonal packs with TD. But people tend to cry about it, because developers make them think about their performance and actually play the game.
