No, not at all. There are many things at play atm.
-Azurite is the product of Gorshalach (Sargeras' sword) infusing Azeroth with death energy while Azeroth itself is chaos, the titan of chaos. So what happens when death and disorder mix according to warcrafts cosmic map? Order is created, represented in the form of crystals and u can see exactly that illustrated on the charts interaction between the both.
- The horde v alliance theme is an intentional misdirection. Blizz has played horde vs alliance xpac hype before, MOP. The real threat was the remnants of y'shaarj and our fucking up pandaria by trying to get some sort of advantage on the other faction. This leads to next poing:
- Hakkar the soulflayer, Queen Azshara, perhaps even N'Zoth will make an apperance. The real threat is under the sea.
-Keep in mind that every world tree is a portal to the emerald dream, it is a way that whatever is in the rift of aln can come into our realm of reality. Perhaps the burning of Tel'drassil may not be an act of war but Sylvanas trying to save us from something. Remember Il'Gynoths quotes about the 5 torches to light our path, perhaps that means 5 trees destroyed and having their blessing wards fail and ushering in the rebirth of the black empire.
Anyhow, this is all fun to think about.
