The last similar leak was also by someone claiming to be Chinese and they used similar riddles in WoD and Legion, Legion also included picture riddles. Things that strike as odd from it;
- Atleast 1 zone per Continent (Counting Zandalar as MoP and TA as Kalimdor)
- Mentions of Zandalar even though the filter didn't happen till several days later.
- An almost direct re quoting of Khadgar's lines from the new dialogue about the Blood of Azeroth
- Wyrmskin Race which is wack ('Totally just' wishful thinking on my end)
