I remember hearing about them at last year's WWI and it sounded like a great idea at the time. A way to may have your main help out an alt. I would be able to outfit my lowbie toon with decent gear that gets better as she levels. Plus I like the fact they are an homage to classic WoW by taking their names and graphics from weapons no one ever uses anymore.
Oddly I don't know anyone in my guild who uses them but I'm pretty sure someone out there is buying them. I see lots of people regularly clustering around the sellers in Wintergrasp Fortress, diligently checking which item they want for which alt but it seems like the only reason to buy them is if you're an altoholic.
With this in mind, I'm curious, constant readers, did you buy heirlooms in order to make leveling an alt easier? Are they worth the expense? Did they make it easier to level and did you reuse them with multiple alts? What if you've never used them before, do they seem more appealing now the new items have been revealed on the PTR?
