"Paragon of Vice" is indeed included in the Ouroboros version of "There's a sucker born every minute".
As I was working on my regular Ouro badges, I happened across it by accident and thought to myself.. "I've been on this arc for a while now, and I find out it's a badge mission. I hope I still get credit for all the challenges I've set for this!... Well.. now I feel like the arc is living up to it's title!"
lol, but it turns out I got the badge for the mission, as well as all the challenge badges when I was done with the arc as well, so I killed 2 birds with one stone, without ever even knowing I was running the badge mission.

That page will show you which arcs the badge missions are located in, but the number of missions it shows for each arc seems to be wrong because the Ouro version of the arc is sometimes different than when you run it from the contact.
Enjoy, and good luck!
I ran the arc, and received the badge at--I believe--the 3rd mission. I completed the arc for the merits(something like 26-29 
)
The plastic tips at the end of shoelaces are called aglets. Their true purpose is sinister.

So, I'm working on my "Marshall" badge for my brute, and wanted to know something. I've used Ouroboros to get quite a few badge missions under my belt (since I out-leveled their content on my way up), but when I went to look for the "Defeat All Arachnos Personnel" mission (by Willy Wheeler, level 15-19), I couldn't find the exact mission. The only thing in Ouroboros that I saw was for the story arc "There's a sucker born every minute", which seems to not have that mission in it.
Am I overlooking something about this? Am I missing something? I'm looking to get the "Paragon of Vice" badge so I can get my Marshall badge, and accolade.
Any advice would be appreciated! Thanks!
