It would be cool if you could check a players level, which could just be a factor of their Pokemons level divided by how many Pokemon they have. I like inviting people I see along the way to duels (usually I know if they are stuck in the same cutscene as I am they are likely around the same level) I think some sort of indicator of the other players XP would help alot with community engagement and so I know I'm not about to get stomped.
