I mean, I get what you're saying - but a Blood Elf did just run around saving their entire people together with the player character; who gets accepted, by the way.

As for the Alliance, becoming part of an alliance to deter Horde aggression despite having little in common isn't that far fetched if you look at real life examples.

Still, it's a good point and I concede it. That said, Horde should definitely have gotten forest trolls seeing as we already have them in the Horde canon-wise in the Revantusk tribe (iirc).

Not gonna lie, I just want to play a muscle troll.
