I'd really like another ice-themed expansion.
But what do you think would be best, a Southrend or an update to Northrend?
There's definitely support for placing a southern cold continent on Azeroth, as it's a planet like any other with cold poles. Because Northrend is more like Antartica than the Artic, due to having a landmass of rock beneath the layers of ice, perhaps Southrend could be a floating glacier instead?
Think of the possibilities!
