Looking through various people's examples they are all full of "project mismanagement" items. If you aren't doing a relic/glam/achievement now, you don't need it. Also, if you haven't leveled crafters then the likelihood of you needing ANY obscure crafting mats in the next 12 months is vanishingly small. The reality is a lot of these items are actually pretty easy to farm once you ACTUALLY decide to do the thing that needs them. Just get rid of them, and during that break between 9.6 and 10.0 when you actually decide to do XYZ, farm them then.
