It would be really helpful to know when a character enters a realm, and when they log out. This is so that an app knows when it is useful to show or not. For example, you might not want to show anything on the character screen as it could be intrusive, and you might only want to show overlays when they are actually in-game.
The following information attached to the Enter Realm event would be really useful in identifying who the player is so that the experience can be customised for them:
- BattleTag
- Region
- Realm
- Character Name
