LW 260-300Follow

Anyone know of a good guide or can tell me the easiest way to lvl without having to do mainly Dragonscale patterns. Also where can i get more patterns after the trainer runs out in Aerie peak. I made a few Green dragonscale Breast plates but they're expensive to make and the materials arent always available. I'm trying to PL LW and will be buying from AH most of the time when i can. Any input will be much appreciated.
