The one thing you can't fault Nexon for is their consistency.
They consistently shatter expectations by being so incompetent and they consistently disappoint people when they try to compensate for things they mess up. There have been people saving for months for DMT, and if you believe they were just shooting for uniques then you are a fool. They obviously were saving up to use to get Legendary as people's time is valuable and being able to effectively double the efficiency of what time you put into the game. They had months of feedback knowing the server was growing, and chose to do nothing to prepare it for the first DMT. Then, shockingly their "code optimizations" did next to nothing for the 2nd DMT runback and they cancelled the rest of them out of complete embarrassment.
