The /feed command for farmer plus makes sense, considering that on the previous server, the VIP rank, which is equivalent to farmer, had /feed. They also had other commands such as /craft, 3 /sethomes, /back and such. Granted the farmer rank now have /hat, but since this is now a premium server, where premium accounts can change their skin to their liking, the command /hat kind of defeats the purpose. So adding more permissions to the said ranks would be reasonable.
Just thought I'd put my opinion in this matter.
