Let me preface this by saying that I was one of the people making posts defending Nexon after the last DMT fiasco. I felt at the time that their oversight on the issue was understandable and that at the very least they had tried to communicate with us and tried to come up with a solution.
At this point, all I can really ask is for Nexon to 1) fix the game, or 2) just extend the duration of DMT. If there is some reason why Nexon cannot fix the underlying issues causing this event to be unplayable (poor coding, DMT messages, who knows), it stands to reason that DMT should have extended time-slots. Based on what Nexon has told us to date, I am under the impression that there is some specific reason why they cannot or do not want to extend DMT past 1-hour time slots (especially because Nexon Korea already does this). Not an expert, but server strain or something along those lines?
Hoping for some more transparency from Nexon this time, but its getting more and more difficult to remain optimistic.
