Friendship level 2021


All information about Story are wrong now (like 2-1-9, does not exist, stop at 2-1-7, and 2-1-7 enemies are not at all the correct ones).
So, anyone knows if friendship rewards are still the most interesting one ?


Honestly those don’t work very well; just farm on let’s fight every day. In a week you can get a unit to friendship level 3+.

Any other way to farm besides let’s fight?
