If you choose two or More Guaranteed Perks in "Rolls with Guaranteed Perk List" Difficulty then we will obtain them on different weapons, not just one of them.
If you need two Guaranteed Perks for a single weapon, you need to choose the "God Rolls List" Difficulty and Choose a Roll there.
To obtain Desired Roll our Team will complete raid encounters every week on your account and also will try to obtain some extra spoils of conquest after raid completions to get extra rolls on the weeks. But we do not guaranteed that we will farm raid for extra spoils of conquest 24/7 to grind your roll all the time.
If you didn't find the God Roll that you need or you want a unique Roll then you should contact our Support Team.
