Elite Zone Expeditions

The world of WoW is incredible. At the current leveling rate it goes by all too quickly. I was thinking it would be awesome if zones became attuned to top level once level capped for Elite Expeditions.

Expeditions could be of varying difficulty and group size; from solo missions returning to check on the status of towns you once saved, to 25 man objectives killing the leaders of new threats encroaching on the region. Guilds could progress through Elite Expeditions, as they do raids with the 25man objectives rising in difficulty through zones (eg. Barrens/Westfall relatively simple, Desolace much more challenging, not necessarily in the current order of relative difficulty to avoid just replaying the zone climb.)

I think this could bring new life to the whole of the world at level cap, adding more content as players and guilds progress through all of the world's zones in daring expeditions. This would allow too for the evolution of each zones story upon revisiting.

Thanks for reading! :) What do you think?
