Make a place where you can trade in overage resources 2/1 for any other resource. That way you can balance your resources. Maybe add some resource packages to the shop or a 2x drop item. Somethings to help in the resource department.
Ok so when you boost your hero lvl. It costs 7 x more to boost a epic hero into your hero then a basic. Yet the exp reward is exactly the same. Now I just want green gems to boost levels. Should have more exp for boost if it costs 7 x more to boost. This should be fixed.
The game is pretty decent. However, just like other comments the prices are outrageous. The reality is that it is all about slowing down the game . They took the best ideas in tower defense and created a system that charges taxes at every turn to go faster. I can pay to play but not if it costs me $10+ just to upgrade a few minor things. Lower prices by 10X an you have a winner here.
kings packs drop more rare cards then anything else. I was expecting more legendary and epic. Many packs I open contain4 rare and 1 epic. That is more like elite packs. Why shou8ld I pay more for a pack that basically ha the same drop rate as elite packs? Give me a good reason to charge ad I will otherwise I think there is no god reason to charge anymore to this game at all. In many ways feel ripped off b the kings packs. I was expecting more.
