We see where the faction war story is going yet again. "We must unite against Azshara"; "Azeroth is dying"; "only the combined strength of the Alliance and Horde could defeat this foe"... Anduin is hoping for peace, Jaina thinks,that Teldrassil has to be avenged,but is ready to work with the Horde,"cause Sylvanas is the reason of what is happening". We already can see that it's a matter of time until the both factions will sign a peace treaty - which will be broken by the Horde an expansion later.
The question is - would it actually make sense to make such peace? I don't know what Horde could do,to redeem itself in the eyes of the night elves. Combined force of the Horde,commanded by Saurfang,marched up until the Teldrassil and did not have a regret about doing so - most of them "enjoyed" it. Would be interesting to know,how many of them fought side by side with night elves against the Legion and how little effort Sylvanas needed to make,to ignite their old hatred towards the night elves. Anyway,I can't see how the night elves could shake hands with the Horde now (and it doesn't matter if lead by Sylvanas,Saurfang,Baine,Thrall...) and say "well,I didn't like that tree anyways,shit happens". The only thing,that would make sense would be the division amongst the factions,but I doubt that will happen - the active subscription numbers are crumbling and dividing the two existing factions into smaller ones would be quite devastating to guilds,communities etc.
Despite that - it would actually be the sole way how the story could unfold if Anduin will value the peace over his allies and sign a peace treaty,thus spitting in the night elven faces yet again - Sylvanas supporters could join her "Horde" which would consist of forsaken,goblins,mag'har etc.; Saurfang/Thrall/Baine leading the "original Horde"; Tyrande's Alliance,which would consist of the night elves;worgen;draenei and Anduin's Alliance. Nothing else,not "Sylvanas was mind controlled"; not "Azerite made the Horde bloodthirsty" or other bullshit would make sense.
And what do you think?Is the peace after everything,that has happened in this expansion possible? If so,why?
