There has been some dispute lately as to why exactly we are awarded badges through raiding. I believe it is time to retell the forgotten story of how badges first came to be.
Ten Thousand years ago, a mighty bear descended upon Azeroth. This was no ordinary bear, for it was known as Thy Awesomebear, and it was awesome. And the elves, tauren, trolls, penguins and gold farmers saw that it was awesome.
One faithful night, Thy Awesomebear was having a kegger with a shark. Yes. A shark. He was just THAT awesome. And in their keggerness (which was awesome), they decided to try drugs. Not just any drug, however, none other than MORONGRAIN, the fabulous herb later farmed by Fandouche Bonghelm, king of the dorkheads. And as they ignited this (un)holy weed, the famed Raptor Jesus Rockstar appeared before their eyes. And they saw that it was Raptor, and they exclaimed in unison: "Holy cow! This is goooooooood shit!"
R. Jesus, unabated by their unsecure drug abuse, smiled upon them in His raptorness and said: "Yo dawg, I herd yo like killin' demons'n'shit and pogs, so we put some epic pogs in yo demons so yo can pog while yo pug." And he threw a tossin' bunch of pogs at them and they reveled in His raptorous pogness. And then they set them on fire, tempering them in the Flames of MMOChamp.
The pogs were lost. Set into the world by Raptor Jesus, tempered in the Flames of MMOChamp by Thy Awesomebear and an unnamed (but flying) shark, they were stolen by a bunch of bi-curious gnomes in pink dresses during a beach party held in flippin' Burning Steppes. The gnomes took off with the pogs, forming the Fellowship of the Pog in the process and proceeded to travel to the mighty Blackrock *dodges anti-racists* Spire to destroy them within Mount Spoom.
But this was not to happen. Nelthafariuson the WE CAN'T SPELL HIS NAME dragon attacked the gnomes, sold them to Burger King, and claimed the pogs for himself. And he brought them to his next LAN Party and showed them to Salandria, laughing at her disbelief. But he underestimated the elf kid because in an instant of AWESOME she pulled out a Barrett 50cal and shot him in the goddamn face. And she took off with the pogs.
Hiding in Shattrath for fifty years, Salandria one day met a frisky dwarf who was thrilled to find someone of his own size. They travelled together for many minutes, and came upon the Caverns of Time. There, hauling the bag of pogs around, the Bronze Dragonflight set their OMFGAWESOME bronze eyes upon Salandria the pog wreckah. Their eyes, which were bronze, glared in awesomeness induced by a shiny brown color. This awesomeness radiated pure bronzeness as the guards (who had awesome, bronze eyes) seized the elf chick kid.
"Stop!" Yelled the fat dragon lying under the hourglass who I totally can't remember the name of right now. "I will not hold her responsible for who she will do or fail to do in the future." And the guards let her go and Salandria went back to Shattrattrattrattrattrath City. The pogs were taking into custody by Michael Jackson who totally lives in the Caverns of Time, where he played with them when he was not busy molesting entertaining kids. But in his dying breath in the year of our lord 2009, he dropped them into the Supermegaomnipresentalistic timewave dimension that engulfs the Caverns of Time. And they were washed in time. And this took time. And just as it was about time, the time-washed pogs emerged in the city of Orgrimmar. And this took even more time. And I am so tired of writing the word "time".
The pogs emerged. Set into the world by Raptor Jesus, tempered in the Flames of MMOChamp by Thy Awesomebear and an unnamed (but flying) shark, and washed in the timeline timewaves of the Caverns of Time, the flame-tempered, time-washed coins dropped onto the head of an Enhancement Shaman in the city of Orgrimmar. And just that moment the servers were brought down to patch Patch 2.0.1 onto Live Servers.
Time stopped. Everything froze for roughly 15 hours cause Blizzard sucks at maintenance. Then, when the Enhancement Shaman logged back in, he found the pogs to be on his head. And he reveled. And then he equipped his double Deathbringers that he had just looted a week ago. And Kanye West, who was a rogue, saw this and yelled "Yo Idontliketwohanders, Ima really happy for yo and Ima let yo finish, but rogues had some of the best dualwield of all time!" And he Mutilated the shaman in a Level 60 1v1 Skirmish (Aka duel outside Orgrimmar), and the world exploded in Kanyelicious mutilation. And the bag of pogs exploded.
The time-washed, flame-tempered pogs were spread all across the world. Everywhere, raid and heroic bosses picked them up and went "Wow! This is a Rick Astley pog!" and took them into their dungeons. Even Outland, because Kanye West is just THAT good at Mutilating.
Then the raiders came.
Everywhere, raid and heroic bosses took permanent brain damage. And the raiders found the pogs, and in a complete and utter rickroll carried out by Ghostcrawler, they took them to their badge vendors (who were all Thy Awesomebear in disguise) and cried: "WE WANT FREE EPICS!"
And they got free epics.
And though there was some forum QQ they kept on getting free epics because frankly, one does not argue with Thy Awesomebear. Not over pogs, anyway.
And this is why we get free epics every patch.
