Another thought I had.  Usually with minecraft, when it rains, I sleep the next night and get rid of the storm. with the amount of players we have(which is awesome) the chances of 50+ players sleeping is practically 0. so storms drag on forever, exasperating the skelly horse problem.  Would it be possible to just dial down the frequency and/or duration of storms thereby reducing skelly trap rates and moving the server out of the rainforest?  (also inb4 optifine eliminates storms client side)
