i would say make it optional to turn on, personaly i dont want my pets/heros to have a buch of comments on them.
if its NOT optional i will NOT support. as i said i really dont want my pets to be turned into graffitie. (fixed my typo x3) As we do have to look at our pet to explore them even if its only for 2 second, we would be seeing the graffitie eveytime we want to swap a pet.
edits instead of making a new post to reply to the one below: or just make it to where if the owner even wants comments to be able to not have them, cause if i have to approve them its the same as messaging the user to begin with.
