In WoW there are quests that you can do once per day or once per week. The weekly quests are raid quests (require more than 1-5 players to complete). Some of them are relatively easy, like Sartharion in Obsidian Sanctum, some of them are harder, like Malygos in Eye of Eternity, or Jaraxxus in the Trial of the Crusader.
The rewards from these weekly quests are also proportionally better than the rewards from dailies. But besides the rewards, one of these weeklies gave me an opportunity to complete another achievement. Reea is now Champion of the Frozen Wastes.
Whee! I've been wanting that title since Wrath came out and I got the last boss (Malygos) on Friday. All thanks to my guildies who came to do the raid weekly and helped me get the title at the same time. I feel so incredibly lucky to have such awesome guildmates. First they help me get the Glory of the Hero, and now the Champion. I <3 them.
Then, I went and helped a guildie to get his two Frost emblems for the day and Skadi dropped Reins of the Blue Proto-Drake. I won the roll! Incredible! I'm still high on the amazing lucky roll to win this rare mount.
The reins are such rare drop that I had never even seen them before. I had seen the mount, and admired it from afar, thinking that I'll never get it. And now I got it the very first time it dropped!
I am a lucky, lucky girl.
