What UA needs is a card for those who do not care about PQD or PQM because they have more than enough. They ought to have enough 1K/GS where a specific product makes sense that offers things 1K/GS do not already get anyway.
My UA purchases go to Amex for 5x MR points ... unless UA brings a card product that matches that and offers additional perks ... I see no reason to get a UA card.
