I understand sometimes its not necessary, and sometimes people just want all the XP for themselves, but seriously, there are times it would be incredibly beneficial to EVERYONE if they grouped for a quest and they still won't.
Today I was in felwood trying to kill those entropic beasts. There's literally 100 other people around, none of them in groups, all fighting in this tiny area trying to get the kills, and NO ONE is willing group up to make this go a little faster. Are they all chinese and can't understand, or am I missing some other point?
