It's a crucible map, the intro to it, when your flying to it, looks so awesome. They have to make this an actually map, not pvp

I was wondering why I hadn't been able to find an Mercury cards despite the grimoire having slots for them. Immagine my surprise when I played a Crucible match on the world. I guess we will get there eventually. I'm kind of disappointed in finding out so soon, though. It's fair to assume that Mercury will be included in the first expansion since the PvP maps are already here, if not sooner. Kind of limits the surprise.
