They signed a ten year contract saying they have to produce new content for that amount of time. I understand that we all are wanting more, but if they threw everything out at us at once the wouldn't make the ten years. Yeah it's getting a little stale doing the same thing constantly. And this idea sounds awesome. I'd like to see a mission where the fallen or something attacks the tower. In every good game at some point the enemy invades your base and you have to fight then off. It could be an event like queens wrath.
