no kidding.
they can't keep their lore straight.
you know that part where Azshara held tsunami??
1. WotA trilogy - she used one hand and in other wine
2. Legion - she used that scepter which was one of the artifacts for healer
3. Warbringers: Azshara - she used her two hands
or how Tichondrius was fighting during WotA but in the most detailed version of WotA event (trilogy books) he didn't even appear.
