Before WoW we had things like Asheron's Call and Everquest which did have open world pvp. If anything open world pvp is the outdated concept, because people like you do nothing but "kill noobs en masse." Battlegrounds was an answer to griefers like you, because killing someone almost defenseless isn't pvp, it's pathetic.
This game also has world pvp; stop picking on noobs in Huttball and get to Illum.
Anyways, I agree with almost everything OP said, although there needs to be another bracket besides 10-49, needs a 10-29 as well.
