To be honest... I expected more from completing the final mission... Although I did enjoy it. Frida caused the most problems (her attack was 16, defense 18), I had to replay it about 10 times. I liked the final battle the most! If it weren't for the blinding and mind control, I wouldn't even know how to fight such DARKNESS and such a HERO. There were no problems with the others...
Well... thanks to Nival for the enjoyable experience, but there are some noticeable flaws. For example, there is a complete lack of balance in the hero levels when capturing Inferno cities. If people knew that all the heroes provided to them in the scenario would participate in the final mission... there wouldn't be any problems at all. As it is, some people had to replay half the campaign just to properly level up a hero for the finale... Nival's motto "Let the player have a beautiful experience" didn't quite work here...
