But the Skulls weren't major components of another mode that Bungie wanted us to play. I wouldn't mind if they were just minor Easter Eggs, but they keep making a big deal out of them, and it feels like they're just pushing the mode on us more. It would be like if Treyarch kept feeding in loads of Zombie related items and achievements into multiplayer to get more people to go on Zombies mode. I'd prefer if they just let the modes stand on their own merits and not start shoehorning them into other modes.
