World of Warcraft is more than just a game. Over the years, an entire ecosystem surrounding the game has developed, created by the gaming community. I've read a few WoW novels and comic books, seen fanfics and fan art featured on the community portal, and I've enjoyed so many awesome pieces of WoW machinima. It's actually quite common for the community to influence the game itself, as we've has seen countless changes implemented after community demand. The fan-created Leeroy Jenkins video, for example, still represents WoW for most of the world.
When I first started playing the rogue, I watched a lot of rogue-centric machinima. Boss encounter videos weren't very popular then, and so most of the machinima was based in PVP. I watched in awe as Grim annihilated everything in his path. I laughed as Happyminti stomped on characters who were 10 levels higher than himself. I sat agape as Hector leaped off of the tower of Karazahn after a mage who tried to escape. My style of rogue PVP has always been colored by the finesse and grace of these rogues, and that still holds true today.
