So I just traded in some of my gold-cards for a cobalt-card, hoping that I would get something great out of it.
What I did end up getting was 3 useless perks (for that class) and the worst gun (I might aswell just use the standard loadout since it has a better weapon and perks on my Cobalt are useless pared with the merc).
My question: Are there any reason to aim for cobalt-cards at all? If there is not then why on earth have grades on cards like that?
