They are not mythical creatures. They roam among us. It could be your best friend. It could be your spouse. They are mean, green, spam machines. They are the Forum Trolls.
For a game like SWTOR, that has such a huge following, official forums are a perfect playing ground for these creatures. Like on every other forum on the internet they share their ideas and defend them with utmost dedication. Reason is not something you can face them with. They will repeat their requests like mindless drones until you give up. Being the vocal minority they constantly apply pressure to the community managers and game developers. Some less resilient game devs might even cave in to their demands. Some game devs might choose to take the easy way out (like in the comic above).
Still, Twi’lek strippers that are dual wielding Jedi assassins with smuggler blasters does sound appealing. Not sure about the big frame travesty though.
