"If someone is going to take my city they should have to do it by taking it from my cold corpse. There should be a grand assault and fighting in the streets not because 48 people ran some quest faster than the other team"

You totally misread. There is a grand assault, and there is fighting in the streets. The "quests" that you are competing to do is are PVP in nature, not PVE. Your objective is to kill defending players, not kill X amount of npcs.
