Suggestion: Tabard that gives XP bonuses based on # of 110 toons

Many folks that have multiple 110 toons, especially once you hit the 5-10 alt range, feel leveling is tedious. Hell, half the userbase seems divded on the leveling speed of the latest patch, hence all the threads on the subject. But allow me to offer an alternative.As someone else said, as good as the book is, once you've read through it 10 to 20 times, it loses some of it's charm. For the folks with multiple max-level alts, there should be a way for Blizzard to allow the leveling process to be faster.So how about this? Create a tabard that you can buy for gold that gives XP bonus stacks based on how many 110 alts you have. Like 10% more XP for every 110 alt you have. That way, the veterans that have lots of 110 alts can equip said tabard to level faster and cut down on the grind, and those veterans with many alts that don't want the leveling speed to go faster, don't have to equip it. Win win for everyone.Thoughts?
