I find it really cheap that in missions the opponent usually have 3 raigekis 3 volcanic fires and 3 white holes with 15,000 plus life points. it would be great if there was a way to get good cards without grinding so much or spending real cash.
It feels like the strategy for winning one battle is the the same for winning the rest of the battles. Get a lot of money buy a bunch of soldiers and win
Having a lot of characters to chose from can be really fun but if one has set of characters that one normally uses and then chooses to change characters then those other characters are weak for the lack of fighting they have done and it takes a lot time to level up the character;therefore, I propose the characters that are not in use level up automatically so one can take them to new battles and not die also leveling up characters with old enemies gets boring.
