I think what annoyed me most about them is that the destroyed areas never recovered. Don’t the races of Azeroth believe in rebuilding.
For instance Auberdine was never rebuilt, and they’re still giving new arrivals to Darkshore the task of rescuing the survivors.
You’d also think that the forces of natural erosion would wear down those jagged cliffs along the rivers on Darkshore eventually. But no, they’re still as jagged and implausibly steep is as they were the day Cataclysm was released. You’d think Deathwing arrived yesterday.
