I have to admit... I thought I would see the typical "Remove LFD/LFR", "Remove flying mounts" and "Only one raid mode: Heroic" sort of crap, but some of those suggestions are actually reasonable. However, the fact the OP thinks that MoP is a fun and lighthearted expansion indicates that they didn't bother to actually play or even read any of the lore associated with it, as MoP is pretty dark the moment you get through the whole "Chubby pandas who love to eat and drink beer" part, which takes only a couple of quests on either side. Can't really comment on anything else as I've never liked PVP and have never except a few weeks been on a PVP server, so don't see what all the rage is about World PVP, and I could care less if they did anything with BGs.
