There's a different take on PvP in LotRO called PvMP (Player vs Monster Player) You bascially get a secondary "Evil" character to play with if you want when you get your main character to lv 10 in the game. This Evil character you choose starts off at lv 50 and you can train him and equip him just like your real character. You go around doing evil quests and fighting high level "Good" Player characters. On the other side of the fence once your real character hits 40 you can participate in PvMP on the good side and fight other evil player characters.
