I think it's a general consensus that this game is a beta for H5. The previous complaints also tie into them saying they can't add visible ranks in game because of their interface. It seemed 343 was a good sized and well funded organization but it looks like most of the resources were spent on developing the new story and Spartan Ops.
Don't be silly.
Everyone knows Halo 5 is a beta for Halo 6. --- This sig will self-destruct in 3.... 2.... 1.... Thank you for your time. Cookie? ^_^
