For the new relic weapon quests, I'd prefer less farming and monotonous tasks, and more of a focus on class mastery. My suggestion would be a short series of quests for each weapon, with each quest having a highly challenging solo duty, something that will push you to the absolute limits of your capabilities as a player. This way, the weapons retain a significant value, as owning it for your class proves you are a capable player with that class. It would also give more people the drive to reach their potential for what will likely be a bloody beautiful weapon.
