Hello again community,
After internally reviewing the Rumble rewards we share some of the sentiments brought up here and in other external communities.
We are not happy with the way rewards are surfaced in the current Rumble. In future events we will better display the best rewards first. We also hope to better message that stones can be turned into random cards of their respective level - Epic stones turn into a random Epic card, Legendary stones turn into a random Legendary card, etc. The team is also reviewing how to make stones more clear and interesting as a reward.
We've added The Drunken Clam card as an available reward to the current Rumble, however, as we are reviewing the current reward structure, this may not be a permanent addition in future Rumbles.
We are planning to include more and more events in the game and some balancing is going to be required as we add more content and rewards to the game. Thank you for the ongoing feedback as the game continues to grow.
