I'll be honest if you want SE to answer this tell everyone playing the game to stop doing end-game since it supposedly doesn't and won't work - SE can see statistics of what people do, if they notice no one able to do end-game or progress they'll see the "severe problem", otherwise...as always, what the vocal group of people say compared to what's happening in the game is obviously a clash of standards which is why SE hasn't "responded to the game being unplayable" as this topic would lead someone to believe.

As the OP says: "It's a major flaw that no MMO community would accept", yet people are doing end-game just fine. So as I said you more than likely want to try to get people to boycott doing broken content if you want to force an answer.
