The moment I looked at the thread's title, I had this feeling there's trolling going on.
In fact, if you combine two or more very famous/controversial/dead horse topics, like "ranger healing, spectre nerfing, summoner buffing, Cyber, mounted combat, etc. in our case Extra large worlds and Exclusive content, it immediately becomes trollish. No matter your original intention.
As far as I see it, there is no need for any exclusive content at all. The consoles had their own, and only bad reputation and flaming rose in its wake. Then PC said "I'll show you how to make real exclusive content" and then the console players got jealous, but we all know the story. Everyone should get the same content, PC, mobiles, old and new consoles.
On topic of Extra Large worlds, I don't think 505 Games could implement them properly on their own (no offense) if even Red himself had problems with it.
So, no, to both parts of the suggestion. I don't see why we should carry on about this.
