It’s actually pretty cool. So gear can no longer titanforge and there will be a max set of pieces you’ll want to wear that have corruption most likely which is fine. You’ll pick whatever the best ones are. I like this a lot so far, adding in gear with effects like this is so much better than having random 30 ilvl upgrades, I only hope they remove RNG sockets as well.
There will probably be a balance to strike between how common/rare it will be to get the corrupted gear but overall I definitely like the kiss/curse idea.
And no, I don’t believe we’ll run into a situation that’s stated in the OP. There will certainly be a middle ground where you pick whichever corrupted affixes benefit you the most and wear those, there might even be Min/maxing with picking an item that doesn’t benefit you the most but also hurts you less. Similar to the rings where you’ll pick whichever effect harms you the least.
Edit: I do wanna point out that this could easily be worse than TF considering it’s still RNG but seemingly more overpowered. We’ll have to wait and see but RNG within gearing was the issue with TF and I don’t see that going away.
