Football season is coming to a close, and once the bowl season is over I'm going to have nothing to do for most of my "me time". So I'm thinking of getting back into WoW after about a year off (though probably only casually). What I was hoping is that someone could possibly get me up to date on any info that would be useful to me right away. I was fully up to date with everything up to, and including Cata, and while I played MoP for a bit, I was not overly informed about things. One thing I will not need help finding is class mechanics stuff, I'm sure I can get that myself very easily. I feel bad asking for such generic stuff, but I feel this is one of those "you don't know what you don't know" kind of things, so any help would be appreciated.
On an unrelated note, if anyone has a good read on the next expansion, I would love to see it. Though I will likely just end up drudging through the WoD sub forum when I have the time.
