Yep, exactly. D2r ladders go the same exact way they did in LoD... Ber and jah runes seen in under 6 hours of the first day and lots of them. The people selling them also sell badly rolled basic runewords and stuff for huge mark-up. They also can find a single base and dupe it as many times as they want, because white/grey items don't have a unique ID until a runeword is made in them.
As the ladder goes on in weeks they post gg rares and other stuff their bots rolled with duped crafting materials, as you can dupe as many pskulls and gems as you want, they don't have a unique item ID.
Rune drop rates improve.
Bots self leveling improved.
There is no duping in D2R most likely. You would see signs, instead 99% of people are making bot find threads, rather than high rune only threads
Unless you think they're taking the time to change item defenses, and rolls, and give them separate ID's lol
