Dalaran? Human city, two times hub. Neutral.
Theramore? Major alliance city... Destroyed with a "cutscene" of a goblin dropping a bomb on it (why not do it to all the alliance cities then? Seriously, who the FUCK wrote this?)
Vol'Jin? Eats an arrow, names Sylvanas warchief (Really? Lol...)
Kil'jaeden and Archimonde just reused, tired. Hopefully they are really dead and this isn't a setback this time.
Zul'jin? Boss in an instance easily forgotten.
Thrall? Pointless Mary Sue. Had to pull him out of the Horde and sideline him because he was getting so tired too.
Archbishop Benedictus? Lolcorrupted.
Khadgar-Turalyon-Alleria = All neutral ('cause that makes sense and writing is sooooo hard)
There's no war in warcraft. Can't write that one faction wins because it pisses off the other. Can't make real changes to the world. Gotta keep the status quo.
WE HATE EACH OTHER BUT THE REAL ENEMIES ARE OUT THERE SO LET'S HOLD HANDS TEMPORARILY! BEWARE WE WILL GO BACK TO BEING MEAN TO EACH OTHER IN THE NEXT EXPANSION.
But in the one after that... There will be another foe that will force a "temporary" truce.
