So many many things I disagree with in this thread but I I want to answer the question first. Who is the Alliance? It is an ideal.
" Using the weapons forged by their new allies, the Humans made haste to prepare for the onslaught. While Dwarven cannon were being loaded, others armed themselves with Elven steel and mail.
Now, united in arms with new allies against a common foe, Mankind stands at the shores of destiny and awaits the coming of the Tides of Darkness."
People might say “aha this is proof the humans are the stars and take too much of the limelight” and I would say that is because the humans started the Alliance and does not make the other races less valuable. If not for said dwarven cannons and elven steel the humans would all be dead! Not to mention the Alliance focused first on saving the dwarves/elvens before it even attempted to take back Stormwind.
On this note, the Tides of Darkness book pretty much explained what Lothar hoped for when all was said and done with the Horde, he wanted an Alliance that did not care where you came from. He was moved by seeing the various Alliance soldiers which came from Stormwind, Lordearon, Stromgarde and even Alterac working and treating everyone as equals!
The Alliance is not the UN. As I have said multiple times the Alliance is closer to the EU more so then the UN. The Alliance has free trade between its member nations, free movement for its citizens and even common laws(particularly with the military).
That Alliance was composed of mainly of humans, humans who had slowly festered animosity for each other. A supreme commander is not needed in the sense that most of the Alliance races are working together because they want to. Further more, even if that was the case, Stormwind’s defacto leader was the supreme commander. And as Metzen himself once told me, the high king is equal to the Supreme Commander. Hell, Turaylon has the position now.
I would argue the dwarves has remained relevant to the narrative. Moira in particularly makes multiple apperances in books and comics.
The dwarves have never cared for leadership of the Alliance and considering the Three Hammer stilll have difference, I doubt any one of them would want the other to be elevated to such a position.
Brann in particular was active in helping the Alliance exclusively. We even have an explorer’s league base that fights the nightborne and the Reliquary.
Eh, I would rather have gnome content focused more on fixing their stuff(ie getting back all of Gnomeragan) and repairing it fully.
Did you even read the some of the flavor text from BfA? Those prespectives are already present. From people who want nothing more then to stop Sylvanas to other like say Shandis who actually wants to move on and doesn’t want her mother to be consumed by her own rage.
Find me a human that is a great warlock, hunter, monk, rogue. And with Varian dead I don’t even think they have a warrior as renowned.
This has been answered before. The humans have a natural affinity for magic. Why? Who knows, maybe it was a benefit from the Curse of flesh. Like it or not, the humans are Meta wise the first mages of Warcraft(tracing their mages to Warcraft 1) and Jaina is more of an outlier then the standard. Heck, even Medivh thought she would be the best mage the humans would ever produce.
The point of the worgens as far as the Forsaken are concerned is in my opinion to prove they are BETTER then the Forsaken. That unlike the Forsaken they have managed to keep their humanity and that unlike say Sylvanas, Genn is willing to bend abit and choose the more neutral, we don’t have to have to like each other but we don’t have to kill each other either.
Then I don’t think you really know the draenei at all. The reason the dreanei are living in the Exodar is because they do have a connection to it. It is almost a living being to them. The draenei are also not trying to leave and some have literally made new homes from as far away as the Hinterlands to Ashenvale. The draenei are not running away any more.
