Yeah, pandaren were more "chill" than let's say the scourge, but MoP as a whole really wasn't chill, apart from the aforementioned short exceptions. You had the Horde and alliance at war from moment one, almost deswtroying a local god in the first zone. Dread Wastes was literally "Icecrown but bugs"and with the first patch the faction war was in full swing, with both sides drilling and mining the land.
