Sylvannas outside of the Forsaken and the Horde is a dangerous element. Yeah if she just remains in the Maw then it would mean that she is not dealt with.
Problem is that Sylvannas as a character has too large of a fanbase. So will see her return at some point.
Repairing relations as the “daughter of the sea” is one thing. But should Sylvannas learn in the Maw the means to create new Valkyr this brings back the threat of Undeath to the Alliance.
The Retribution Paladin artefact weapon demonstrates the Light consecrating the graves so that the dead will remain dead.
Calia Menethil has betrayed the living of Lordaeron. She done nothing for long after the fall of Lordaeron and simply showed up in the Priest Order Hall during Legion.
This is not something that will sit well. But perhaps finally the living people of Lordaeron accept they are not a country or people anymore. Or there is a new ruler that they can rally behind.
Sylvannas done so much damage to the living including the Horde. However there will still be Sylvannas loyalists. Even among the living of the Horde.
It is a real chin scratcher how Blizzard will move forward.
Yes you are correct. 7th Legion not S17.
The Wildhammers could help to rally the scattered remnants of the High Elves. Some High Elves lived in Theramore before it was bombed by Garrosh.
The rivalry/hatred is mainly pushed by the Silver Covenant but there are other High Elves outside of them.
The main confusion is that there have not been enough distinction between High Elves and Blood Elves.
When it comes to the Troll Tribes the difference between Sand Trolls - Frost Trolls - Jungle Trolls is obvious.
High Elves as a race are not part of the Alliance. 7th Legion and Silver Covenant are just random groups and individuals doing their own thing.
