I can only assume more champs will be added, so as a fun exercise, I tried classifying every champ

This isn't a definitive, absolute list or intended to be balanced (I can only hope that the dearth of options would mean re-balancing certain synergies like Noble or Phantom). Again, these are just my own conclusions, and you can definitely argue some of them. This was just a fun exercise, a little game in itself; putting things into categories is fun for me. That being said, there were some champs I just couldn't pigeon hole (mostly the tech-based ones). Maybe an Inventor origin in the future?
