Runescape isn't known for embracing teamwork. I hate to make a WoW reference, but for people to embrace teamwork, there will have to be a better friends/clans system. In WoW people commonly go on intense 40 man raids that require each player to do something essential to kill the beast, BA was trying to do something like that, but apparently that just isn't what the average runescaper is looking for in a mini-game.
