Wowtrack not updating rus not updating
This is the item someone received from their weekly mythic chest in their order hall.
As you know the weekly chest reward is based on the highest mythic dungeon completed that week, so you can use it to determine what their weekly highest mythic level was.
I keep seeing people asking how websites are tracking the amount of mythic dungeons completed, so I decided to make this post. For the people that don't know, you can only track level 2, 5, 10 and 15 mythic completions because those are the only achievements available.
As far as I know there's currently no records in the character statistics endpoint related to mythic dungeon completions.
The news feed can however contain multiple "challenge-mode-jackpot" news feed items.
