The competitive community must be thrilled with this update.
It really is a shame. I guess it's cool, and it's another thing to kind of take care of but there isn't any need for it. There are plenty of games that introduce some kind of pet system where they can be of some valueable use for quests or maybe even in BK or PK.
I was fascinated by what the streamer responded with when replying to a question. I think it was a question about the dogs being able to do more things or fight, and the streamer said, "Not right now, but blah blah blah-"
This may be an indication for something more inclusive than simply walking the dog around the world.
There are so many ideas you could put together with pets. So many quest ideas, maybe a pet could be useful and help for certain types of bounties in order to save lots of time.
Maybe with the stats included with the pets, perhaps a new system could be included to a similar degree. Right now, nobody needs to do anything to take care of their character and there isn't any real performance value for how your character is since there aren't any statistic values for players, only pets.
