WoW only recently, in the grand scheme of things, got the LFG tool. People got groups and raids way before the LFG came into play. I personally find the LFG tool horrendous as it hinders server communications and interaction among people in the game world. No longer are people questing and meeting up and making friends. They are now grinding until level 15 dungeon leveling and sitting inside of a Major city doing nothing. Gone are the days of actual MMO story line driven game play and that is why this game will succeed.
