Here is an image of my sons latest base defense. He is a level 71 and the attacker ( names and stuff removed ) a level 103. No medals? He won a lot of those lately, no medals.
I am used to it on my account as well, but since medals count for little, it does not bother me.
It does however show that Kix cannot get the simplest thing right and further do not have the capability to ascribe a meaningful purpose to a feature that should have a meaning. Lost opportunities.
