Cross-play is so many years too late, I don't even care anymore. If this had been implemented at the start, and it looks like it was thought of, otherwise why provide for cross-platform clans, we wouldn't be talking about this now because this stuff would have been ironed out as we went along and PC came into the picture.
Who am I kidding? It would have been as ironed out as anything else in this game has been, which is to say st(r)eamrolled.
In any case, the only people who care about this topic are the people who've been clamouring for it for years and the people who either tacitly or actively dislike the idea based on PvP concerns. Everyone else is like, "Whatever, dude, I'm just trying to grind out this Uber-Stick of Snicker Snack. Where do I have to go to next and how many do I have to kill, and should I do that before or after I bake cookies for Zevala?"
