Here I am with another game where everyone played well, and I'd actually like to acknowledge this with good feedback for everyone possibly. Could it be that there would be a way to do this for everyone at one time? Obviously not negative feedback... people would be out of control with that.
Feedback should be unique and individual to the person, not just a copy/paste, which is precisely why you can't copy/paste when leaving feedback. If all you want to say is "he played a good game" to everyone is it really worth of a feedback? Why was the player good? Surely not everyone was good for the same reasons? Make feedback unique to the individual. Sorry, but this idea is rejected.
