I had heard that there may be an option to lookout, maybe like while sailing on the seas. I have always said that we need a crows nest.
I also think that more pets will come. If you look at other games with pets, you can summon them there. So, Disney's version would be to have a potion to summon them. I can see this expanding in the future though so that you will not have to use a potion to summon your pet.
I do have a question though. Why is there a ghost boss in the new caves on Raven's Cove? This leads me to believe that there will be more quests added. All the other bosses we have to fight at one time or another in a quest to obtain something. Just makes sense that this new boss would be required kill in a quest.
