Realistically I do not expect anything from the current team, because the alliance they see, and the alliance I played as, are fundamentally different. What the alliance is in the eyes of the current narrative lead:
“The Alliance is like a family. Brothers and sisters can disagree, and things can get heated, but there’s still a deep and abiding love and trust there.”

That was never a theme of the alliance. Being family-alike was the origin of the early WoW / W3 horde. The approach both easy to emphasise with, yet flawed because things like nepotism can grow from it.
Similar was the alliance one, also with something good, but some flawes. A good summary was given yeas later, but still true:
Justice is something easy to consider good. Indiscriminate justice can be both satisfying and flawed.
I’d argue it was this contrast that originally made the faction concept work. Different ideas. Different strong point. But also, room for error in the things that are not bad by themselves.
So, what do I mean by that? That I do not care much what would the retail team do, because they do not get nor care why I started playing the alliance in TBC days.
But, if in some miraculous way we might get a team actually interested in going back to what made both the alliance and the horde interesting to begin with, then maybe it would be nice to revisit those things with more polish first.
So, I’d say, looking back would be the 1st thing to do. There are many changes to actors and motivations, so digging out things long lost might reveal some things, modern players do not even consider.
