Legendary Reputation and Instances

Instead of adding more groups to gain reputation with and grind the same dungeons and raids on, why not have high level players unlock more reputation with old factions, like the home cities. At a certain point, the highest level players could unlock exalted, pushing it to 3600 rep or something, and then have Legendary as the rep catagory beyond that. As a way to gain reputation, I think that each dungeon and raid in the game that is not aimed at end game users, so all the Classic, BC, and WOTLK dungeons when Cataclysm comes out, with the exceptions of Shadowfang Keep and the Deadmines, should have a Legendary setting for end users. It would be a heroic version set for top game difficulty, so for Cataclysm it would be for level 85 players, but it would be set higher for later expansions. you could get quests for doing battle in these dungeons in the major cities, like putting additional NPCs in the Hall of the Brave, Hall of Legends, or Grommash Hold in Orgrimmar. They would give a limited number of quests, say one for each run to a total of three quests per 5 man dungeon, to kill a certain number of trash mobs and the final boss, thus 'clearing' the dungeon. These quest turn ins would be the only way to improve reputation past exalted with the different factions, in this case the capital cities.

Each quest turn in would get that person reputation and an emblem or token to buy end game non-set gear and recipes from the home cities or other factions. I imagine that to keep it from being a grind, each 5 man would only have 3 quests or something, with older raids having a 3 10 man, and 3 25 man quest options; and nothing else would drop in the dungeon but trade goods and vendor trash, maybe, possibly recipes, but not epic gear. The epic gear would be from the tokens or emblems and only the quests would give reputation, not the kills. Players could also gain reputation with other end game content. I just think that it would make it easy to not have to grind reputation with 15 more factions for Cataclysm.

And each Legendary dungeon could earn a guild an item, or whatnot, that would give bonuses, or be helpful, like an extension of the guild leveling system. For example, guilds could earn guild trophies from the legendary runs of dungeons. For Ragefire Chasm, guilds could earn a trophy that is an off hand item that when held gives all guild members in a raid or party +5% to Demonslaying. The trophy from Hellfire Citadel: Magtheridon could be the same, and so stacked. The trophy from AQ40 could be a hold raid Nature Resistance. And so on, for all dungeons.
