I like to make groups, and I like to lead them.
What I do not like is the constant management of the group interface when people drop, log, ragequit, etc. (I also do not like pikers you can't boot on a chain quest). It just cuts into play time, and adds a level of management that, really, should be optionally handled by the system.
No one I ever saw in Stormreach has changed their shorts since Korthos, and no one has ever starved to death or died of thirst, so micro management could be eliminated from other areas as well.
I would like to suggest a more dynamic group window. It would make it easier for everyone. Specifically, a simple checkbox to automatically update my group as to the quest I am on, and to auto fill it with appropriate members from my checked LFM selections.
That easy. It dynamically updates - refuses the guy who is too high level, and lets me focus on playing instead of managing a system that has not adapted to the player base and grown with the game.
