In the example below only Bronze and Silver cards were on offer. Previously you used to get the chance of at least Gold cards here.
7th Day reward still says chance of Cobalt card

Yeah, I feel like, overall, since the last update, we’ve lost chances to drop very rare loadouts. I would usually care to play the whole 7 days thing through but I don’t feel like it’s worth anymore since there’s very few scaling in the rewards now.
