In what way does it matter if you're good at PvP when you're wading into a sewer of 200 people killing everything in sight? I mean seriously. It's fun but no one is "good" at that. It's not like there is some Conan dude in the middle sweeping all his foes before him.
Well, unless he's Vengeance DH but that's just making up for the wimpy monks which were making up for the ridiculous OP of DKs back in the day.
