Honestly I was really disappointed with the changes of the reward structure in Bronze league. I understand that the bots were a huge problem, however, after the changes I had little incentive to play the game. My collection worth $470 so its not like I didnt put money in the game, but I had the feeling that the new players were ignored in favor of the whales (these pre-sale events didn't help either). So I just rent out most of my cards and play a few games to get to Bronze II.
Yesterday season rewards were quite surprising and gave me a much needed incentive to not give up on the game.
I was used to the 1-4 credit rewards and potions. I hope in the public sale I have the chance to buy some packs too to get enough power to play in silver.
