Kabam take off a month.
With the building bugs and stuff not working and just pure crappy content. Take a month off.
Take a month of and do maintenance on all content. For that month you could have Forge be the new champ. You don't even need to release Forge just have him as the story teller and the whole month is just side events. Fix one piece of content and make the new side event a test of that content and you have your plays show you where the problems are. And just keep rotating between bg, aw and aq, and fixing the AI, incursions, arena, and other content. This is a perfect chance to have a very minimal month event but still something we all can do, and gives you the chance to fully focus on fixing everything. This will greatly improve the quality of the game and people may actually like playing again.
