Of course, with the onset of dishonorable kills and in-game civilians, pretty much all of that finished. No self-respecting PVPer would dare to tarnish their record with DKs (with some exceptions, of course), and even high levels, met with resistance by NPCs, will often give up the ghost (literally) rather than continue the war where it's not supposed to go. But are we better off for it? Or should DKs be done away with?
Not surprisingly, the majority of players (the really vocal ones on the forum, anyway) want them gone. There are a few benefits to keeping players from attacking certain NPCs-- a few players have suggested keeping DKs only in lowbie, 10-20 areas, which would probably leave Crossroads off the list. Other players say them's the breaks-- if a 60 undead mage decides to make things hard for people turning in quests in Goldshire, all fair in love and Warcraft. But the majority of players agrees that even on PVE servers, the DK system has to change. There's a war on, after all, and if you can't kill the other side in a war, well, what can you do? Those calling for getting rid of all DKs say the World PVP options Blizzard has announced (delivering dust in Siithilius and babysitting towers elsewhere) aren't enough, but when has Blizzard ever steered us wrong in gameplay? Before the BGs came out, players whined, but now, especially with cross realm battlegrounds coming next patch, BGs are humming daily.
But worry not, anti-DKers: Blue has announced that the beta for the Burning Crusade will be DK-free. Could this be the beginning of in-world PVP awards, all-faction buffs for high-level kills, and temporary titles for those who take the lead in battle? Of course, Blue's not saying any more. They always do that, don't they?
