It wasn't even a real race in WoD. Outside of Paragon winning Highmaul, they got absolutely crushed in Blackrock Foundry by 5 days and Hellfire Citadel by nearly 2 days.
Limit's Ghuun was a much closer race than Paragon's blackrock Foundry or Paregon's Hellfire Citadel.
Hell Jaina was even a closer race than BRF or HFC.
But my main point is the gap between world 1st and the world 2nd kill hasn't been as close as it was in Uldir in years. In fact, I can't even think of a race that was that close.
