OK, so don't use the LF dungeon aspect, get players on your server, ask in /shout, /general etc , form groups without using the tool. Gamers decide to take the quickest route to do something(which also counts clearing as fast as possible and kicking people who cant etc),though its hard to fight human nature. But nothing stops someone from forming their own group, getting to know people on their own server etc, they just choose not too. Which is odd because most of the time the "Tools" will take longer to form a group then it would of took to just do it yourself. Players have gotten use to the tool, they demand them and cry foul when they are not included.
You can't do anything about players clearing content as fast as possible, that shit has been going on since the dawn of games and will never stop. People did that shit in EQ all day, try to kill as much as you can and as fast as you can, then go afk(or what players do today and just tab out).
I wouldn't be shocked that the players that cry for socialization don't even try anymore. They wont talk to or deal with "new players", they don't like players new to MMOs, they choose to just stick to who they know already or just pug it and stay silent. They never try, they never make the effort, they want the game to force others to talk to them, instead of them choosing to talk to others.
@ etch, I wont respond to you, you are still stuck in 1999 and don't seem to want to leave ever.
