8% exp and rep buff today

[JohnGabriel]

Just in case you were not planning on playing today, you will miss out on the WoW 8th anniversary buff.

Would be a nice day for grind boosting.

GDI, I didnt realize it said today only and figured I would take advantage of it all day tomorrow

The item you get in the mail is this Celebration Package .

It is a re-usable item and according to WoWhead comments, should be usable between today and December 3rd.

Yeah, it should be for more than one day. They've been doing this for years now where you've got like a week or so (in this case, apparently until 12/3) where you can log in and get the anniversary achievement and the in-game mail. If today was the anniversary it would technically be wrong since WoW was released on 11/23, not 11/18.
