To me Pandaria has been a sort of lighter themed expansion. No, I'm not talking about Pandas being silly and Blizzard "jumping the shark." I'm referring to the hundreds of silly jokes littering the expansion and Pandaland itself. From "I'll ook you in the dooker" to the Grummles, Pandaria has felt a bit more light-hearted than Burning Crusade, Wrath or even Vanilla. I'll admit I didn't play much of Cataclysm.
I'm personally hoping Draenor is kept as a very hardened place. It appears to be a very barbaric land run my Warlords (hence the expansion title?) and I hope it doesn't lose that atmosphere by Blizzard packing in tons of pop culture reference and silly monkey men. I do know people like that, so I'm just curious as to who is hoping for what when it comes to this next expansion.
