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.
Let the texture set according to the manufacturer's directions, and then use a texturizing knife to smooth out the splatters, flattening them slightly to the wall. Work with a light hand, ensuring you donât create any gouges or uneven spots. Let the texture dry completely.
