You know why I like Warhammer 40k? Because in the grim darkness of the future, there is only war.
No one's is asking "why we fight?".
No one is "searching for themselves".
No one is realizing there is a "much greater threat we must all unite against".
We fight cause we love to beat the shit out of each other with ridiculously huge guns.
We don't search for shit because our faith is in the Holy Emperor and in the Chaos gods.
We'll kill that greater threat and then get back to killing each other, thank you very much.
And it's fucking a great buttload of fun.
Warcraft?
Varian spares the Horde from being annihilated, at least twice. Jaina does the same, at least twice also.
Anduin saves the leader of the Tauren from certain death, then gives his father's sword to a legendary orcish warrior, whose body he carries his into Orgrimmar alongside its former warchief. This is after helping spearhead a mix of Horde and Alliance warriors into sieging Orgrimmar.
Both Thrall and Saurfang claim that this time they are different, and that they are breaking the cycle. Everyone seems to be pointing to wanting peace and unification.
Expansion #5412341 : THIS TIME, it's back to WARcraft. The Alliance and Horde will be at it like NEVAH B4.
Listen, I grew up on Warcraft 2, I would love for WoW to go back pre-Cataclysm and pretend like none of the subsequent bullshit happened (except maybe Legion, that shit was tight). However at this point, the faction war is just ridiculous to swallow.
