I am a big fan of [url=http://destinydevs.github.io/BungieNetPlatform/docs/EnemyHistoricalStats/]EnemyHistoricalStats[/url] which would be nice to see a more detailed/consistent breakdown of enemies. Lots of little obscure uniquely named enemies that are not tracked or get merged into their corresponding enemy class. I still need to build my Enemy Bestiary... I would also like to see more information about the current activity in the GetAccount endpoints, at the very least so you can accurately determine what map, mode, game type, etc is currently being played. Fireteam size would also be handy for checking against people on your friend's list you'd want to join. Perhaps it'd be cool to see what type of weapon damage (Solar, Arc, Void) is being used per kill? ie People could then determine how many noobs are using an Arc weapon when it's Solar burn or the spread of damage when its Match Game.
