Nobody cares about making it “less social dependent”, in fact it’s widely considered a good thing that you don’t have to beg people to help you with some garbage quest or send whispers to 10 groups to not get accepted anywhere, or sift through 50000 dps for your 5man.
Absolutely nobody. People are very social and actually do talk a lot, sometimes even in game too!
They just don’t have to stay online to keep in touch with their friends and communities anymore, and use this privilege to do whatever they want to do with their time, including doing something other than WoW instead.
Oh and by the way: It doesn’t.
