Why has there been a duping bug every season with nothing happening?
There are people listing stacks of runes and boss mats 500-2,000 (less than a week in to the season) quantity and there is ZERO way it is possible to have this many.
How does Blizzard not just look at the trade website and point click ban these people?
The duping bug has to do with stackable items. ANY stackable item works on the same mechanic.
Blizzard canât fix it without breaking stacking. So instead of punishing all players, theyâve elected this.
IMO, moving many items to Materials Tab fixes most things. But Blizzard wants them to be tradeable (boss mats, gems, runes). So this is what we gets.
Other games have stacking without duping.
They also need to insta-ban people that abuse the bug. Not hard to identify.
Yes. But this has been in D4 since at least S3 (this specific method). They literally canât fix it without sacrificing loads of QoL. I think itâs a mistake and I would fix it even if it meant no stacking or trading - but Iâm not Blizzard. 
Itâs likely that the bug is due to a fundamental design flaw in D4 and that complete rewriting of core elements of the game would be required to fix it. Itâs not worth their time or money to do such a thing at this point. Hopefully they will learn from this mistake and eliminate it in D5.
Duping and botting didnt destroy D2 and i remember very well 20+ years ago.
I think its since S2, duping its been with us loooong time, but lazy devs only fix the most important thing.
THE SHOP
Be grateful - just what do you think you would be able to afford if it wasnt duped into worthlessness?
Duping happens to all items, not restricted to stackables. Blizz needs to sort out the root issues and look at innovative approaches to better automatically manage it.
In the absence of that we see more burden on mods to manage it and players to report it.
All of this begs the question why isnât Blizz doing more? Being agile and responsive to the issues as they arise would help - rather than waiting for months to get off their hands.
Surely theyâre getting paid enough now that cash is flowing with the 2 2/3 [ x ] net plat cost increase for the premium battle pass.
Innovative? Have you played D4? They arenât breaking any molds here.
@hex well yeah do I ask for too much reasonable expectation⌠some effort at least would go along way⌠signs of life⌠anybody home⌠maybe some folks from the letâs jack up the price of the premium battle pass dept.
I get what youâre saying but the only thing this argument really points to is Eula breachers are raking in the bulk of benefits in the game by botting for the coin that jacks prices up then duping their warez to get âtheirâ coin back and push prices down.
Itâs your normal players getting screwed on both fronts, they get stuff all resources in comparison and when they do get something cool drop, itâs worth stuff all.
If itâs all too hard for Blizz to address the issues, then just drop the Eula and letâs get a good look at the lay of the land when everyoneâs botting and duping.
I read a post from a China guy back in S1 and he mentioned that the duping exploit utilizes a core piece of the game engine that Blizzard canât fix, they can only sort of put up road blocks which are defeated in hours after patch release. It doesnât help that Activision Blizzard shares their code and IP to Netease.
Unless they change game engine entirely and stop sharing with netease, duping is here to stay, which destroys the âitemâ economy for most players, but the D4 team doesnât make the decisions that are in play here, they can only damage control via in-game mechanics.
Honestly taking as much stuff out of the inventory and into the backrooms (materials tab) like they did with gem shards, and making them untradable and undroppable is the only way to stop duping on certain items.
Duping is because Blizz allows it. The trade sites are funding the microtransactions that Blizz wants. Duping wont go away.
By the way, millions of people played D2 back in the day and used to RMT duped SOJs, Zods, Enigmas. You could even buy Ethereal Armors with sockets on websites. That was 20+ y ago.
That was 90% of the playerbase on D2 battlenet.
To experience the game on its true nature you had to play it Single Player and not on Open Battle Net.
For D4 its the same. If you are using the Discord Trade Website you are buying duped GA items and duped boss mats.
But the fix is easy - just adjust the drop rates! Itâs a simple case of supply and demand, if the designed supply meats the demand then people wonât but dupes, or less people will. As it becomes unprofitable the websites will close down/ move on - no QoL game features lost. This isnât rocket science, just simple economics that a 10 year old can work out 
Letâs roll with the assumption this is the case for a moment.
Why then doesnât Blizz drop the related Eula? Why do they ban some players for their involvement?
By trade sites funding mtx, do you mean the participants that sell dupes on these sites are also RMTing? And youâre saying that funds their mtx?
I think we would need to see that post to draw objective conclusions from it. No doubt it has some interesting comments but the conclusions able to be drawn would depend a lot on the content.
I could offer other explanations based on yeast youâre saying, but it would be best to look at the source first.
Some interesting points on the code sharing to netease. Yes there could be problems such as you outline here, but just as readily there could be answers here too.
I think we can add that to the list of reasons players wanted offline mode in d4. That horse has bolted now though.
To an extent, yes. Then they often end up in the trade channel.
So Iâd take it a few steps further and say trade is broken. They might as well disable trade until they can address the issues better. Remember they used to for short periods.
Its about control. Think about that for a moment and get back to me.
It would be far easier if you could just explain what you mean. Nothing obvious is coming to mind that helps me read your mind 
Shrug, one of the reasons why I stopped playing D4. I just found it too tempting to buy stuff with real money because it was so inexpensive due to the duping.
it was just a setup to fail.
Keep in mind people who buy mats and stuff on the black market, probably same people buying skinsâŚsoâŚLOLZ?
Macroninja gets credit for this deduction btw.
