Sorry to write my question in this thread, but it is the one that comes most close to my issue, since I have not posted enough to be allowed to start my own thread.
I am on the first map ...still, enjoying going through the story and searching through every corner I can get into, not to miss anything. Now I have noticed 2 battles until now with each with an optional, the battles themselves is super easy due to my army setup, though terrible hard to get the optional(s) done ...and I failed them both. I feel there might be a reward or achievement hidden behind doing them ...will any unlock for easy revisit be available, because I really don't feel like playing through the game 10 times or how many tried it will take to get the right army setup and card draw needed to get the optional(s)? ...now don't get me wrong I love the story, but I am the kind that only goes through story 1 times usually, depending on why I need or do not need to repeat story, I might push myself through 1-2 more.
