Two major leaks have been floating around for quite some time now, and they are of course The Dark Prophet and the Council of Glades. If the expansion turned out to be one of the two, which one would you have it rather be?
Council of Glades
We only actually know of the trademark but people have already started assuming that it has something to do with Lordaeron, Tirisfal Glades and/or Sylvanas. So based on that information alone, is it an expansion you would want to see?
The Dark Prophet
This leak is a little more fleshed out, and to put it simply, it more or less holds the same concept as Eye of Azshara, just with some added trolls and twists. It's said to be the long-awaited South Seas expansion where we get to see nagas and pirates and explore the uncharted territories south of the border. You can read the leak in its entirety here.
And if you're still confused, or somehow managed to miss all the leaks over the past couple days, I might recommend Bellular's videos on both The Dark Prophet and Council of Glades for catching up.
So, if it had to be one of the two, which one would you prefer? More darkness and dead things or tropical isles and blue seas? Personally I think a South Seas expansion would be a nice change of color palette after Warlords of Draenor.
