First, Watermelon event was mentioned because it generate funny circling dialog when Gameforge was saying about correct database values and players were complaining that actual drops were not what they should be. This kind of interaction surely can inspire certain ideas about game team. But this is not issue in question and let's focus on the stats.
First, where can one see the "official" loot tables? I mean those published or confirmed by Gameforge . I hope you are not soliciting players into inspecting client files and violating ToS section 3.3 or taking third-party information for granted.
Second, we are again not on equal footing here.
Have you tested distributions of all drops? Or at least those proposed earlier?
Players cannot make thousands of pulls for free. I got suspicious after spending almost EOJ points cap for chain and leather items in Chassizz. Have you tested those? What was the expected distribution? Did the real distribution pass statistical criteria? These questions don't seem to dispose your "really internal" info and answers will be much appreciated.
Or maybe you tested just one particular distribution. In that case request for deeper inspection is reasonable. But shell items would be a higher priority as well as PoM gear.
As you can see answering that way is getting the discussion nowhere. Although it is a good way to bury the conversation when one party has to make may guesses without prior knowledge and another can happily give short comments without any actual information. Just compare the size of your last response and the number of options i had to consider making mine.
I hope we can do better than that.
Looking forward to anything you consider helpful to keep players informed.
