Guys stop supporting fleece farmers and just do linen darkstalkers leve for your fleece needs. If you don't need exp you can quickly synth 9 of them and turn it in for 18 fleece, which would take you like 15-30 minutes to farm manually if you did manage to nab one of the sheep fields.

Only reason to farm sheep is if you want HQ fleece, but high level/properly geared crafters with the right cross skills don't need HQ materials to create HQ yarn.
