Have you guys made fun of WoW yet? Considering the game has a "leather chest" too. And as mentioned above, high = high defense, low = low defense. I played this game for the first time when I was 13, when it released, and I knew that right away. It's kind of common sense...Sorry to disappoint.
BTW, I recommend you guys try getting the grasp of the entire story line before laughing about "demons" and "monsters." There's a LOT to the story, and once you learn the story, it'll all make sense...Like the part where they didn't know the main guy was a "mystic" - it's because the common human on the game doesn't even know what a "mystic" is yet.
--and no, don't go taking this as being a "jerk" - just trying to say to think before you speak. It does help. To TRY and find something to laugh and complain about can make you say some stupid things, lol.
