fishing for spread royal road is a 2/3 chance. the current seal system makes you fish more than royal road ever did.

Also worth pointing out: The current system is not all or nothing. You still get a DPS boost even if you don't get the cards you want.

The old system was all or nothing. RNG might just decide you get no boosts at all.
