Halo 5 forge

Okay I know that halo 5 doesn’t feature split screen. But what’s up with having an Xbox live gold membership to access forge? What the bleep! We don’t even need to have anot her player to forge. 1 person can dish out an incredible map by himself. It’s like 343i is making us but xbl gold to experience the better part of halo 5, the multiplayer. At least give us forge as an offline feature with your -Yoink- campaign that gets old in 2 playthroughs.
