TB's not some ridiculous troll who goes out of his way to anger as many people as possible and tries to piss off his fans, it just bothers me slightly that he calls Charr cows.
I mean, he says he does it to annoy us, but it's not like spiteful "I'm going to piss you off as much as possible and try to make you hate me lol I'm a troll umad?" kind of trying to annoy us.
I hate you now.
I guess I'm not much better, I didn't give them enough thought to think about WHAT they were. They were just.. Charr.
But Minos? Come on now, there were ACTUAL minotaurs in GW1.
