You said that you have to be 80-85 to get heirlooms. On my first char ever (undead rogue) i played a lot of random battlegrounds and i got the pvp shoulders. It takes time but it was totally worth it :D. And btw great guide.
You can smooth the hard edges of a selection by feathering. Feathering blurs edges by building a transition between the selection and surrounding pixels. This blurring can cause some loss of detail at the edge of the selection.
Open the photo with the rough edges in Adobe Photoshop CS5, and then select the Blur tool from the toolbox. Step 2. Hold down Alt and use the mouse scroll wheel to zoom in on the section of the image with the rough edges. Alternatively, use the Zoom tool to view the jagged edges from close-up.
