If you're too lazy or don't give a fuck I will make a short summary. You do four quests - you gain four tormented weapons. Which means more rewards for GW2. That's why I guess it won't be hard to gather a strong PvE army to do this business.
Everyone who wants to follow along, please write your name down. We can complete these quests some evening.
I am sorry to disappoint you guys, but the rewards from GW1 are just some useless skins that you will never put in use in Guild Wars 2. Therefor I don't think that there is any point of wasting our time, or at least mine. :D
