Quitis, before complaining about the game, behave yourself when playing. I hate those Mr. Do-nothing when they are losing the games. Your are worse than dropper!!!
to Kostitsyn: u will reallize the card gaining rate decreases at higher level... anyway, i would say it is easier get bored if u collect all the cards too easy...
One question about the cards: I know the devs are trying to balancing the cards, but one question is that now are the same cards gained in different way work the same?
e.g. deadly poison (Tiki artifact), with "K" card it is 80% chance, yet with "R2" card it is 70%....
