I'm not sure if you're trolling or not, but in Diablo 2 there were quest markers above an NPC to indicate that they have a quest for you. I don't think all of them had this as I think it was more for follow up quests but I remember it being a thought bubble with a "?" and they moved closer to you when nearby.

Secondly, a good portion of the quests in Diablo 2 revolved around 'go to x area and kill x mobs' quests. In fact, the very first quest you get asks you to kill all creatures in the Den of Evil. While there were still quests to explore and retrieve items, the majority required you to kill something. These quests existed in the first Diablo as well in quests such as The Butcher and The Skeleton King. One could say that the evolution of quests within Diablo is changing with each new title and, over used as those quests may be, having no 'go to x area and kill x mobs' quests would make one boring Diablo title since that's what you normally do anyway. How a quest such as this can make anyone moan and groan or be shocked by surprise has either never played a previous Diablo title or is arguing for the sake of argument.

Torchlight has these quests too, given by Trill to go to x area and kill x mob.

Bottom line, Diablo 2 came out four years before World of Warcraft so, if anything, World of Warcraft simply 'refined' certain elements found in the Diablo series such as the quests, interface, and talent tree. I know a lot of people hate Warcraft but think before you jump on the bandwagon to compare titles for the sake of bashing.
