90% of my REQ cards never worked.

So today I have come to the conclusion that basically all of my reward cards never worked. So I have basically wasted 50+ cards on nothing.
I really do not care about the XP ones compared to the rare+ cards that are supposed to give you packs.

So no one should probably be using their cards, unless my game is just jacked up and im wasting all kinds of -Yoink- on nothing.
