Anyone have a recommendation on when is a good time to farm Fleece? Every time I try there are at least 2-3 people farming the spots north and south of Dragonhead where they spawn. With that many people farming it will take an awful long time to get a full stack. I see people selling multiple full stacks of 99 on the AH all the time. I assume there must be a "good" time to farm, otherwise it must be taking them forever to get that many.

Thanks,
Jawn
