D4 announcement guys said they’d never do balances with PVP in mind. Not that thats 100% they’ll stick to that, of course.
Diablo PVP has never really been “supported,” it’s just always sort of existed. D4 is the most we’ve gotten, with dedicated zones, and items, but it really amounts to being able to kill monsters to get ugly cosmetices while trying not to get ganked by easy mode barbs.
Maybe by D6 there will be actual PVP content lol
