Not sure if this is feasible, but would it be possible to make some type of fountain of youth that is either quest or crown based that would allow de-aging a pet and allowing the chance of different talents being learned?
So if I get a really crappy talent on a pet I have put some time into I can take the quest or whatever and they would revert to something like halfway through the previous rank?
That actually sounds pretty cool, although I don't know how much it would actually affect the game, and if most players would actually use it. Yes, it's a cool idea, I just don't see many players using it. Who knows, I could be wrong, this is just my opinion.
