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.
Exfoliate one to three times a week with an exfoliating brush or a scrub with smooth beads. Mild chemical exfoliants, such as glycolic acid, beta-and alpha-hydroxy acid, or fruit enzymes are also effective at improving skin texture.
