As I said it is not enough, the night elves have pretty much just the same leverage as the average troll nowadays. It is nice for a small storybeat, but won't fix the underlying issue, if we don't actually get to see what the factions truly are it is just as hollow as the burning of teldrassil itself was, it meant pretty much nothing except for cheap shock value.
It is just blue beats red this time, you have the main storybeat, but now you need perspectives that bring this conflict to life. The night elves should by all means hold a grudge for one of their generation and act on it, meaning trying to drive the whole horde from kalimdor, meaning generations of innocents will die in the future, this will properly muddle the whole thing.
Add internal conflict to it all and finally flesh out the races, with defined traditions rites etc.
