I'd suggest, when a player have a level higher than max allowed on a duty, s/he being synced not to the max level, but to the min level of the duty, for the following reasons:
- High level synced players makes the duty too much easy and the new player hardly learns anything doing that, most likely he will be carried on;
- New tanks haven't any chance to hold aggro against the above players;
- High level synced complaining about those duties too much easy, here get served little more difficulty
