I believe that if a player attacks another and loses the attack (no stars) then all of the items that they took (coins, alloy, etc) should be returned to the player who successfully defended their base.
I do not see the purpose for a player who has successfully defended their base to lose the thousands of credits and other things...
For instance, a player recently attacked me and he only got 31% and he lost. BUT I was the one who really lost because even though I got medals for the successful defense, I lost 230,000 coins, 145,000 alloys and 8,000 contraband..... So even though I won the defense, I still lost.
Players who attack others and lose should only lose medals and those who successfully defend their bases should only gain medals. They should not lose anything for successfully defending the bases.
