I agree; unless you're a profession nut (like me), far better to buy the craftable directly off the AH, or just the mats, then level LWing. Farming just doesn't scale the way dailies/quests do. Although you can kill tons of mobs, you still end up mob starved with more than 2 toons relative to how much you _could_ kill, plus you still have to loot/skin 'em all one at a time.

Most of the level 78 LW blues take about 10 borean heavy leather and 1 eternal water, that's no more than 40g in mats in the Bonechewer AH, or 3 level 80 dailies (10 minutes?) on a single toon. Pretty easy to find someone to craft em for free if they are skilling up, or for a modest crafting fee. Should be able to afford the whole set in a couple hours of dailies or quests at level 80.
