Calm down! It's really easy to earn Gems by doing the daily quests. If you do 6 quest a day that give you 10 gems each you can buy a 100 Gems pack within two days. (6x10x2 = 120).

But I do agree that playing the campaign doesn't give any reward when you've completed the coin collection. But when you play Ranked mode you can earn Gems by ranking up and even more Gems by going to the next leaque.
