(And I'm personally already losing a bit of hope when it comes to the Extreme Dungeons because Bluehole most likely would not allow good loot in there aswell).
I don't think BH give a damn about the loot rate/good loot on a version they don't run themselves, if you see what I mean.
You also forgot how this game and especially the cash shop had been managed by the former CM/Don'tRememberWhatHeWasAtThatTime which is now """game designer""" for GF.
To make it clear, I'm not saying that the developer is out of any responsibility. If the game is trash, according to what you said because I haven't played for a while (and was wondering how it turned out, thank you for the partial answer), it's probably mainly their fault, but, contrary to what the staff is claiming (and some palyers thinking), not t only, far from it.
