Not getting all legendary cards after finishing a 500 wave run

Title pretty much says it all. I never got the second ring (ying/yang) nor helm of hades. Also, it feels like the droprate decreased, previously you had almost all purple and orange cards at wave 300 (i think) now you get them all through the game. is this intentional? Hoid

Hi Hoid, yes this change was intentional. It's still possible for all uniques/legendaries to drop, but less likely. Hoped to make the endgames a bit less the same. Cheers Andy
