It'd be nice if we could increase friendship level of not-so-useful heroes who still have the +10% bonus effect from the dispatch mission to get some bookmarks from the reputation and also unlock the facial expressions and voices for collection purposes.
This game doesn't follow the conventional 'Commander' system but the friendship level sorta does it seems. In most games missions like Dispatches where you aren't directly interacting with the units has no affect on affection.
That being said, I wouldn't mind this feature but it makes sense as it is.
I think there's no reason why it shouldn't be in dispatch missions, seeing that the lowest time for one is half an hour, why not just make it so that they give a certain amount per half hour, it really would be good to see the expressions for heroes like Nemunas and others that I don't use, because I'm a completionist as well, need those expressions!
