Is there a place where we can see what the chances of getting a card is per win? I'd like to compare the previous rate to the new 5.5 patch increased rate.

Additional suggestion: Have a pity timer for each card for the number of wins needed to get that card because RNG is really unpleasant. Take Memeroon for example, such an easy NPC and it could take hundreds of wins. It really is unpleasant, and when you finally get it, you don't even feel satisfaction, it's just "thank god that's over".
