When is the update of Deathwing

Hi, as the title of the topic suggests I ask politely when do you plan to update Deathwing. Currently the state of server prevents people from playing any challenging pvp due to bugs and issues with core mechanics. Everyone talks about it, everybody complains about it but none of the players tries to act to do something about it.It's been year since the realm is in such a condition. As I have found, you promise to update Deathwing with Lordearon updates hence the question is when do you plan to do so?

There is no specific time to do so, but the core of both Ragnaros and Deathwing might be updated in the upcoming weeks.
