Think about it, shouldnt legendary items (only) scale with level? Look at Thrall, still lugging around the doomhammer. Thats an old weapon... if it never scaled he would be pretty weak. How cool would it be if all the time you sunk into getting a legendary was rewarded by letting you keep it all through-out the expansions. Personally, I think my shadowmourne is pretty f'in cool and it makes me a sad panda that its probably gonna be gone, knowing blizzard, at lvl 81.
