Dear Kabam, Friendship crystal rewards are...
Not worth it. Getting just one (not 4) makes sense as you clear your first rounds each cycle. I’d make the minimum rewards more than 3,000 gold. To put it in perspective, i have 18m gold so this reward is like not winning anything.
Maybe make an uncollected version for players further along in the game? The 200 5* shards you also get are meaning less and less. That is 1/50th of a 5-Star champ.
