I would have addressed this point earlier, but I must have skipped your post. I have a lot of things to say to that analogy and I’m very long-winded, so here we go.
You say playing the Alliance is like getting your favorite food. This is a great analogy, because if you only eat your favorite food, it stops becoming your favorite. Try eating it every day for a month and you will absolutely agree (or you won’t, just to be contrary). You need variety to make your favorite food actually enjoyable. You need things to compare it to so you can remember why its your favorite.
That’s what the Alliance without conflict and drama becomes; a bland substitute for your “favorite food”. When every major story arc is the same as the last major story arc with slightly different presentation, the story arc loses meaning.
As I said before, the biggest problem with the Alliance story arcs are that they are all either dependent upon or done in conjuncture with the Horde. You either have to fight the latest Lovecraft to stop ragnarok with the Horde, or you have to help the Horde fight the Horde who is essentially the latest Lovecraft starting ragnarok. So much of the Alliance narrative involves the Horde that the Alliance’s favorite food must be “how do we interact with the Horde for the next two years this time?”
Meanwhile, the Alliance takes a second seat in a Horde-Alliance war from the Horde perspective. Under Garrosh it was his crimes and how Vol’jin’s going to overthrow him. Under Sylvannas it’s her crimes and how Saurfang’s living in a swamp. But while the Alliance is certainly a prop to the Horde narrative in our war against y’all, they’re only that; a prop in the play.
It’s not fair to the Alliance that the Horde can dominate their story, while they only get to be a prop in our’s. The Alliance is the side salad in our story meal.
And that’s because, unlike on Alliance-side, we get to have narratives beyond the latest Lovecraft. We get to have the conflict and the drama. While sadly it usually results in half the Horde becoming a Lovecraft, it still gives our faction something to rally behind or against that isn’t a Lich King, a Sargeras, a Deathwing or a N’zoth… Even if Blizzard ends up writing that conflict and making someone a Lich King, a Sargeras, a Deathwing or a N’zoth.
Conflict builds tension, builds stories. While Blizzard seems to think the only kind of internal conflict a faction can have is whether to side with a genocidal psychopath or not, this needn’t be the case.
Tyrande asked for help from her allies in the Alliance and was denied. This would be fodder for great stories post-BfA as Anduin tries to make up for turning away the night elves. It doesn’t need to make either one a raid boss and could showcase that the Alliance aren’t just the Humans and their Amazing Friends. A simple story like this could highlight how humans and night elves place different values on different things and tell great stories about both races.
Instead, because people seem intent on the Alliance being as bland as can be, it’ll all be forgotten by 9.0 and only mentioned by Golden offhandedly in a novel some years down the line, forgiven by the last page. Because oh boy, a Lovecraft’s coming and we can’t have Alliance stories during a ragnarok!
