You've got a magical tree the size of a mountain miles away at sea, but Horde catapults equip their +50000 range + 50000$ gear and burn the shit down to a crisp in the matter of a night?
"It's a game, it's a magical world."
Give me a fucking break, you realize with that kind of firepower they could at any time teleport those catapults in Elwynn and literally blow up Stormwind in minutes?
What the hell were they firing, plot devices to the power absurdity? How many did they have, 10000 of them? What was Darnassus made of, rotten dead wood?
It's just idiotic, at this point a single catapult in Warcraft could probably take out Magtheridon in space in one hit if you judge by this event alone.
