And you dear sir, is rehashing the same old arguement. What you are advocating is that people should manually find group in trade chat like before. What you refuse to listen is that is not an option for some people. For you, this is their problem. If they cannot find group, too bad, no dungeons for them. For people like you, who have no trouble with finding people and friends, it works for well for you.
As it has been mentioned by many people, spamming trade chat for over an hours to find people for one dungeon is not something they want to do. Again this is their experience. Yours is very different because you have no trouble making new friends in tradechat in minutes.
The social aspect in dungeon runs? Sure there were exchange pleasanturies. But once the dungeons run was over, people went their seperate ways. Adding people to friends list? Only if you happen to be a tank or healer. This is not making friends in my opinion, it is simply adding people of value to your list. Again, your experience differs. You make friends easily in your dungeons. That is your experience.
Some people prefer to make friends in guilds. That is their choice. That is their style. You want to make friends in dungeons or tradechat, that is your choice. I personally do not socialize with random people I meet on the train or buses. I do that with peole I meet regularly, like in my guild.
People play differenty. Stop calling people thick skulls because their experience or preference differs from yours please.
