Required Gold and Internet

Alright, so I need to rant here; I find it absolutely ridiculous that you need both an internet connection and a Gold subscription for every mode on Halo 5 with solo campaign as the exception. Not to mention how it’s taking up 1\5th of my hard drive. I understand that every mode like Forge and Custom Games put you in dedicated servers but hello not everyone has amazing internet, some people don’t have internet at all. Not to mention why put me in a dedicated Forge server WHEN I’M PLAYING ALONE?! Just make it so that we can play everything offline with the exclusion of multiplayer of course, I understand they can’t add split-screen at this point, so you’re probably thinking “well why make customs playable?” the answer is so I can test the maps I make. I paid $250 for this game and I’d at least like to play it when I can’t buy Gold.
