I've been doing writs for a while, I finally got a second crafting character maxed out so I can double my chances for yellows and sealed writs. Problem is, I never really farmed for what I got, I just gathered what I did in solo and I've gained more than I've lost. Now I've run out of Nirnroot, and checking the prices, it's nearly 300+ each now. Alchemy writs, besides surveys and sealed, don't seem to give much of value. Should I continue doing them or is it just a money sink?
