When you only have a certain type of player on your game, it feels a lot staler. Even if the roleplayers on Classic never interact with PKers or sparrers, there's still an impact on their game. When you seperate the playerbase based on interest, the game loses a ton of diversity, which sucks. Because of this, I think Classic does the social server much better than a dedicated "social" game would. Also, Classic already caters heavily to the RP community and probably will continue to support them.
