As the title says, the new level scaling feature showcased on the frontpage is likely to be implemented for a way for max level players to revisit old content.
I think the mode will work like this:
-Right click portrait, change raid/dungeon setting to Timewalker
-All high level party/raid members that enter an dungeon/raid will have their abilities and gear scaled to the level of the dungeon/raid.
-This mode does not scale up, and it's primary purpose would be to either allow-high level players to run dungeons with low-level friends or allow a group of high-level players enjoy some old content.
Edit: -Max-level players that complete the instance gain reputation with the Timewalker faction, faction quartermaster sells pets/mounts/tabards as an incentive.
I believe its a fantastic idea, as i don't like blizzard attempting to renew old content (Like zul'gurub, scholomance), and instead just allow you to adjust your own power to match the level of the content.
At least this way they probably won't ruin some of my older favourite dungeons/raids like Karazhan and Dire Maul, and i'll be able to semi re-live them with a group of friends.
Thoughts on this new possible feature?
