Gamemodes?

I enjoy the games mode like a lot of players here, not much for rift playing anymore sad to say but I do enjoy and pay skins when something new hits the store that I like. I also connect to see what game mode is around and enjoy them. One for all and arurf are my faves. I also have a PBE account and loved the last brand new game modes you all created, very good job. Why is it you guys allow for no game mode for weeks? Nothing on both live and PBE... why does it go for so long and what happen to the rotation?
