I dont know if this is possible, but seeing that there will be a town PVP i think it would be cool to have like a town pet to help protect your shops, or shop pets. And these pet could be upgraded by getting certain things or a certain amount of money.
I think a way to speed up crafting, other then buying it, would be a good improvement to the game (it may be in the game already and I have not gotten there yet). Otherwise it is a very addicting game and enjoyable.
