Now that I had some more time to read this, I have another question.
"Increased Credit payout for duplicate items
- Common – From 200 to 300
- Uncommon – From 400 to 600
- Rare – From 800 to 900
- Epic – From 1200 to 3600"
I was led to believe that you can't open epic cards randomly, did that change while I wasn't looking?
Edit: Since I'm still getting XP on this post, maybe you guys didn't read on, so I'll add this: DarthFDG already provided an answer for this, I forgot about the seasonal reward crates for example, those contained epic-tier cards.
