Can we get an API for querying which story mode dungeons a character has completed? Or, inversely, which explorable dungeons the character can open.
You can check /v2/accounts/achievements for the completed paths.
Opening explorable mode is per-character.
I second this motion. Also, adding the ability to track the story chapters per Character. I have to go through each character individually and check which story step I'm on. For most that probably is not an issue, but I do have 17 characters on one account.
