Which Merc group is the best for the Aria T'Loak quests?
I'm trying to decide which group to help out, Blue suns, Eclipse or the Blood Pack. Which group is the best overall for help and supplies?
There's no reason to not simply help all three - every merc group you gain the help of shows up as part of the "Terminus Fleet" War Asset.
I've picked up all three, and the Terminus Fleet is listed at 200 strength.
As far as I can tell, you can help all of them and get all of them to join you as War Assets. I know that I have already helped two of them.
