With the new mob limits, there has been a noticable increase in wool prices throughout the servers. Most wool shops are now selling out, and the price at malls seems to be approaching double (and still selling out). Wool is an important part of many building projects, and there is no replacement in many cases. Many of the largest and most creative creations on the servers were made possible through readily available wool. If sheep were made to drop more wool, this would offset the effects of the limit, and allow for more diverse creations to be built.
