Make more opportunities to get the 5 tier sticker pack. One idea I have is that once you complete all the daily tasks, maybe you could get a tier 5 pack as a reward. And/or make the daily log in tier 5 pack 100% get you a new sticker. Ive been only a couple cards away from completing the sticker album two times now and it gets really frustrating to play every single day and still not be able to complete it. I would enjoy the game and the sticker album a lot more if i felt like I actually had a genuine chance to complete the album and it wasnt as much of a gamble.
