I actually just looked back through the news on the official site, and reread the portion regarding coins. It only mentions an increase of coins in market incubators (up to 65% inc. dependent on level), the arena rewards are only mentioned to have a full 10% inc in value at level 35 (so there's hardly a difference between each single level 20+), and lastly it only seems to increase resource CAPS on darts and coins gained from spinning drops (so not actually inc the amount you get per spin, you can just spin more each day). All other sources of coin income look to me like they have stayed the same. They made things SOUND like we were getting more benefits coin-wise than we actually were. So, in reality, they haven't done anything to really fix the coin problem, just somewhat increased the value of paid-for coin avenues, and threw some change on top of PVP coin-making
