I don’t know if people get as mad anymore for this but I remember the game getting some hate for this…
Tops/T12 Items in the Nexus.
People were getting mad because people could just buy some items from the Nexus, sell them for life or def and then max your Character.
You could make the items you buy from the Nexus Soulbound, like the pots from daily login rewards or something like that, so that you can’t trade them but you can still find them useful.
Feel free to correct me if I made any mistakes.
