For those who are outside of the loop, I come from 4Chan and the Voldemort of forums which can't be mention, some people who work in the game in the past, from writers to artist, have left the game during these months.
Apparently the changes on Kylar, Robin, gameplay mechanics and change of tone (Whatever that means) made them step back in the collaboration of the game, with the main phrase being "DoL is not what used to be". Reasons varied and people who left aren't main developers, are collaborators but some of them work on the game since a couple of years or early development.
Don't shoot the messenger, just mention it because people don't talk about it here.
