No, let's keep it level 60 only please. The whole idea is to use it as an incentive to get end game players to do more older content (although not all content is old). This is clearly shown by the 'first timer' bonus. Of course being able to do things unsynced or solo defeats the purpose slightly but most people just wouldn't do the content at all if they were made to do things like T9 at original ilevel.

There's so much content for non-end gamers to do that they don't require Wondrous Tails. If they feel they do then I pity them.
