There should be a way to see what champions you've killed. Maybe a reward like a skin or something if you've faced off against all of them? Cause I always have to think back to see oh which ones have I seen again? But it would be cool if the game kept track for us.

They should really either 1. take animals out of pvp because nobody uses them. or 2. completely revamp pvp. They should use a co op map or one of a similar size that's just like co op, but you can kill other wolves in solo mode or team mode. Either one would improve the game.
