Since Blizzard doesn't want players farming randoms for reputation, but is apparently thinking about giving a once a day reputation boost of some sort, I thought I would throw in my idea and see what people thought
Tabard of the Klaxxi
Binds to Battle.net Account
Equip: not sure yet...
Use: You champion the cause of the Klaxxi. All reputation gains while in level 90 Pandaria dungeons will be applied to your standing with them for 1 hour (12hr Cooldown, shared with similar tabards)
1 hour rep boost every 12 hours, or essentially for the first 2 or 3 randoms everyday for the average player. Wont necessarily solve the...err...problem?...of only obtaining charms from dailies, but its a start
