I did a search for this and did not find it so please forgive me if this has already been discussed.
1/ Allow mules to trade with other players and bots. In mule form, I can buy/sell as much as I want with an npc but not with another player or bot.
2/ Allow mules to cast tele to portals and tele to range. In mule form, I can use rings to get around but not cast spells to do the same thing. I know you cannot use a ring for ttr - that is just a personal preference.
