Okay, so I got Andreg's whistle, and followed the first quests he gave me, which ultimately took me to the Rohirim camp and I powered through the quest completions, in my eagerness to get to 75. Now I look at the deed mentioned in the title, and see 4 quests I need to complete for it. I asked others and they said Andreg gives them in certain locations while he's summoned, like the ones in Annuminas. My whistle has gone, how do I complete the deed and get the virtue! Others say it warned that you wouldn't be able to complete them if you finished the quest at the Rohirim camp, what's the point in that!
Highly frustrating, I'm sure enough people will have raced through this part, there's only so much quest reading I can do with all the quests given in RoI, especially when half of them have stupid objectives like... "collect slug meat".
In my opinion you should be able to complete the quests regardless, why do we have the multi-layer dynamic thing? Let me go back to the previous layer and complete them! A lot of people are complaining that he doesn't give the quests if you're in the right location with him summoned anyway.
