Found an excellent tool over at quickarmory.com. With all my talks about twinking, this little gadget is a quick and easy reference to finding what stats are given at any given item level for your BoA gear. Useful for comparing BoE gear versus BoA gear for your twinks.
All you do is find the Heirloom Item on the list, then just move the slide bar at the top of the page to the level you are looking for. Easy to use tool that saves a lot of time.
