We all know how reputations work in WoW. You hit exalted and then you get access to epic gear and an exclusive mount. Only sometimes a faction rewards you with something unique like for example Sunreaver Onslaught from patch 5.2 gives you http://us.battle.net/wow/en/item/95590
In my opinion there should be more "social items" (something like this for example http://us.battle.net/wow/en/item/88584) avalaible from quartermaster when you hit exalted with a certain faction. Also there could be items with which you could interact with... NPCs.
For example let's take a look at the item from Feeding the Hungry and the Hopeless quest - http://us.battle.net/wow/en/item/57991 - you had to feed people with it. Afterwards a nice effect was shown on them:
So maybe reputation quartermasters should sell items like this one with which you can interact with NPCs around? Lets say you hit exalted with Horde or Alliance reputation in Krasarang Wilds, then you are able to buy an item with which you can go to the near guards around and when you use this item on them, they salute you, say something and maybe give you some sort of a buff? Wouldn't it be cool?
What do you think?
Also if you support this idea, write something here: http://eu.battle.net/wow/en/forum/topic/7390630250
Maybe someone from Blizzard will see it.
