Since Teamfight tactics and League of Legends are logically within the same universe lore/world wise, wouldn't it make sense to have a creature as cute and iconic as a Poro be implemented as one of the few companions available? The only reason I would see not to is to make Teamfight Tactics more distinct, possibly ARAM companionship problems for Snowdown, or Teamfight Tactics branching lore instead of focusing on the existing stories.
Thoughts? I know I'm not the only one to think this. I've seen plenty of comments on Reddit or other forms of social media.
