The Midsummer Festival is coming! This is my first time experiencing the Midsummer Festival as an Alliance character (I did do some of the quests as a Horde character, but it's been a year so I've forgotten the details), so I had to look up the available quests on wowhead.com
Midsummer Quests Basically, you get a series of quests to find bonfires in various locations (mid to high level regions on each continent, and then successively harder-to-get-to bonfires in level 60 dungeons), culminating in a series of raids on the capital cities of the opposing faction!
...which might be a little tough for us, since we're not quite level 60 yet. ;) But even if we don't get to all the bonfires, we can still enjoy the various buffs we can get. If you're lucky enough to be near a bonfire when someone tosses in a Burning Blossom, you'll receive a nice buff called "Fire Festival Fury: Increases critical strike rating and spell critical strike rating by 42."
