But as I went on, they brought out the Pandaren's idea of, "peace & harmony" due to the sha's presence amongst the land, while we come from a land of constant warring, being within our blood. (TLDR I thought we would be the enemies of Pandaria, with our "originally" bloodthirsty leaders (talking about Varian here) and would have to make amends eventually, with the Pandaren ON the homeland taking sides and warring against one another. Brother against brother, families torn apart and such.)
A can't speak for Vanilla & TBC's story-lines, due to I was too fresh at the time for those, but I can site one from Wrath as an example, (I posted my displeasure with this MoP event somewhere in the mists of time (pun not intended). Stoneplow and The Wrathgate.
When first I saw Stoneplow, I knew that wall's gonna fall, and this town would be overrun. Once the wall fell, I though, "oh, will it be just like Andorhal Alliance and we fall back to the brewery & halfhill, playing the guerrilla warfare strategy, that'd be neat!" But then comes good 'ol Chen Stormstout, and our previous master, and the day is saved.
Wrathgate was unexpected for me, and was what started all this in the first place. The Lich King didn't die to Saurfang's cleave, but actually lost his life due to his brashness. I guess you can say, I love darker and more violent stories in that sense than what MoP has brought to the table as well.
