TK teleports through the Nether. It has to do many ports to reach it's destination, that's why it's journey took so long. It something happened while it's in the middle of the nether the Exodar(if it's really a lifeboat) would have to be able to reach the next planet.
Although that's all speculation, the term propulsion could also refer to the teleport-drive in the first place. The technical details are never really explained, even the function of the Exodar within TK is all speculation.
The Alliance Airship in Icecrown used to have a nuke in it but it was removed for unknown reasons, they have the capability to make them at least.
You've got the ultimate mary sue: Jaina Proudmoore.
She's the most powerful mage on Azeroth, after ToT she'll be infused with power of the titans, easily making her the most powerful mortal on Azeroth.
It has to count as something, right?
I don't think you know what a Mary Sue is if you honestly think Jaina of all people is currently a Mary Sue. She is not perfect.
Honestly I've stopped using the term altogether because of statements like this. It's become a meaningless label as it's definition is far too subjective and when it isn't such as now it's used in a way that it isn't meant to.
Hmmm haven't seen this quite yet... Horde has a nuke but have you forgotten about Jaina and how she ALMOST destroyed Durotar, Read Tides of War. She was ready to kill Men,Women and Children but thanks to Green Jesus and Kalecgos she didn't. Jaina still has the Focusing Iris in Dalaran(Alliance Controlled). So Imagine that, sure goblin nuke did some damage, even tho it it was a small radius. But just think about what Jaina could do. There's no Nuke that can ever outmatch her.
you cant counter it...if our rogues hidden in stormwind sense a newer technology, well be forced to use our nuke destroying yours.
