TBMC has a grind profile that collects 500 of each material, the quest hands 150 of each in, the grind profile collects 500.
however, something to keep in mind, in a week, the korkron quest won't be there, i have no idea if the mobs will be (i assume for a while they will be, but not for long). any of the korkron oil/timber/meat/stone will be vendor trash, and probably the LCoGF will take a dramatic downturn, as will the motes of harmony and gold drops, the 24 slot bags, etc.
and in about 10 days or so, we'll all be offline waiting for the 5.4 post-patch-patches and the hotfixes and the hotfixes after that. so the 14th or so we'll be back in.
by then, we'll need a grind path for timeless isle (and meshes for it too)
