Hi... First of all sorry for my bad English but I am not to good at it.. I had questions... did higher difficulty settings will help my character level up faster? There will be more troops in enemy armies= more experience or the numbers of troops will stay the same but they will be tougher? I want to know if there will be difference in level power etc. at the end of the game between character from easy and impossible difficulty...
