Tom Chilton, the chief designer of World of Warcraft, said, "No more 40-man-raid, because 10 and 25 players raids still feel epic. “What we realized is: it’s not really the number of players that makes it epic, it’s the quality of the content and what you do with this content and what you do, to make players be part of this content.”
Highlights of this interview about World of Warcraft - Catalysm:No player housing system, and he also talked about the new community feature, Dungeon Finder.No more 40-man-raid, because 10 and 25 players raids still feel epic. “What we realized is: it’s not really the number of players that makes it epic, it’s the quality of the content and what you do with this content and what you do, to make players be part of this content.”Old 40-player raids will be recap in Catalysm but not like Naxxramas and Onyxia in WLK. They are excepting with probably much more substantial changes. For example, they’ll use Blackrock Mountain to create a new raid instance within the Blackrock that’s an extension to Blackwing Lair. This area is a completely new area where players have never been before, with a lot of new bosses. It’s not like bringing Broodlord Lashlayer back. 5-man dungeons won’t be rebuilt in Cataclysm but new ones will be added.He commented the upcoming epic MMO: Star Wars: The old Republic.There will be a new patch between Patch 3.3, the fall of the lich king, and Cataclysm, including class balance changes, new Battle. New features, new bosses, but smaller than Icecrown.
