I think it might be a good idea to have full group parsers available only for coil and other serious raiding content, as having good dps all around is a necessity in most coil situations, and players doing this content are not going to be casuals for the most part. I do not think they should be allowed in normal dungeons because it isn't necessary and would lead to certain people being aholes for no reason. Maybe only if it's a preformed party. I think personal parsers should be available anytime.
