I have a short story.
There once was an adorable death knight. He loved Azeroth, but would sometimes get bored doing 3 hours of the same missions for the same people every day for 7-10 months, and would disappear for short periods of time.
Then N'zoth Came! And our cute Death Knight decided to come back and take up the cause again. And then he was doing missions to help support the effort, and realized they weren't the same as they used to be! There were no missions to go kill 6-12 of the same enemy that somehow keeps coming back from the death, every day, repeatedly!
He was extatic, and told all his friends that times were changing! That the missions were finally interesting and different!
Then our adorkable death knight went to Uldum today to help some more with the war effort to protect his home!
And was sent on a mission to kill a bunch of the same particularly healthy enemies again and to pick up trash on the ground that wasn't there.
The Death Knight was deceived! And so ends our story. With a sad sad death knight doing sad sad things.
