For the backlog of content that now comes in two varieties - "brain dead" when unsynced or "still too hard" when synced - a third mode could be added that syncs a full party to 10-20 levels above the content.

This would allow friends taking along new players a better, less punishing experience than going full min iLvl (something that could take an entire lockout to teach) but also make it so that a cool fight isn't dead in 10 seconds once a level of 100s gets their hands on it.

All the rules and restrictions for unsync still apply: No tank points, no experience, no gil, etc, but it would instead count towards a new achievement under Battle for all classes for "Moderation" culminating in a title called "The Moderator." (We don't have a title like that yet, I checked.)

Alternately, it could hook into Khloe's system like Faux Hollows did, since getting enough silver points from 2 lines is incredibly frustrating. But unlike Faux Hollows, this wouldn't require someone to retool the fights every expansion, since the content is always synced down to exactly 10-20 levels above min iLvl.

(This post was inspired by watching Colin and Bethan go through Coils.... and the parties murdering the level 50 mobs in 5 seconds.)
