While it would take 30 seconds for Widijo to be defeated his opponent, the Necromancer takes down in just two seconds. When facing the Necromancer as an Diablo 4 Gold opponent, wudijo is killed just as fast. However, since the cheat requires the Necromancer to stand still, wudijo's team is able to kill him when trading.
The cheating Necromancer wasn't found just in widijo's matches, either. A different user shared a screenshot on Reddit which shows Burn cheating in their PvP match, too. Although this player, Burn, has shown that they have found a method to play around in Diablo 4. if others are cheating as well, there's no evidence provided to the community until now.
Another issue that remains unanswered is whether the trick employed by the Necromancer could be utilized in PvE. It's certainly a good idea in PvEas illustrated by how fast the Necromancer eliminated The Guardian Spirit. It's not clear if it's being widely used in PvE as of yet, but. Diablo 4's PvE leaderboards appear to remain intact, but this could mean that normal players have enough money to remain ahead of the curve of cheaters.
It's too early to know the extent of cheating and exploits could be in Diablo Diablo 4. Blizzard could have an aggressive response to cheaters, however this Necromancer playing through multiple matches without punishment shows there's work to be completed. If cheating becomes excessively, it could prove an even bigger controversy than buy cheap Diablo IV Gold commercialization.
