First: Remember that GREE is a business with employees that they need to pay. So yes, they are going to try to slant wars / heroic mode to encourage players to spend money on the game. Remember, if everything was easy and no one spent money on the game, then they would probably stop supporting the game and it would be the end of K+D.

That being said..

Second: I made it on this last one with minimal gem spending (40 total). It can be done but it takes a lot of work and some luck. You have to be very active, a casual player doesn't stand a chance at the plus version. Also use your friends to get more battles in, or use your potions to get more battles in.
