I would just like to say, that if you are the Leader of a group, you are in control of that group. Just as you would be leader of a raid. Without organization from the leader, the other players run rampant. The Leader needs to identify each player's role before the first Mob is pulled. Are you MT? Are you a healer? are you a DPS? The leader decides who will fill these slots. Sometimes it is difficult to assign spots when you have to group members who can both be tanks...etc, So usually the Tank with the most HP becomes the MT. And as far as two healers would go, they usually speak to each other to decide who will buff who, and who will they primarily keep healed or buffed....Make a group channel, and make sure your group is on it....Better organization is always helpful in preventing the type of gameplay you have described. If you don't care to join a group that has already formed for one reason or another....Then form your own group, with the range of players you want in the group. You may not have a full group immediately, and this will definately take some time and patience....but once your group begins to pull those MOBS the organization will make this a smoother process.....
