The renewed sunders and new unique jewels are, by themselves, a very good buff to all other classes. This is the only major change for other classes.
Gheed's wager is nice on zerk barb and hdin
Sling ring has its place on magic dmg builds
Opalvein is decent on non-fire/light sorcs
horazon glove + boot combo is decent, but LoH still exist... could see it on some particular builds that would need this extra 10 ias/frw
hellwarden's will is decent but can pretty much always be outclassed by other options on any build -> I had fun with it on a bone + CE nec, benefiting from both -magic/fire res (but this is a p1-3 build)
enthropy locket and dreadfang are kinda always bad, even if they look nice on paper
void is not really worth using, except maybe on abyss lock
