Yes quests do offer a break from just killing monsters, but quests (at least in World of Warcraft) seem to take the roleplaying out of MMORPGs. The game becomes more about doing quests and less about becoming emerged in the world. I guess another problem I see in WoW is that many of quests are similar, so it seems like you are doing the same quest just at a different level and in a different area. I am interested to D&D Online because it appears that it will have fewer quests, but the quests will require grouping and large amounts of time. It seems that quests can be very mundane when they are not well written. Thank you all for your feedback, it helps me think and checks my ideas.
