Prohibit receive trophies for losing! It’s not funny anymore. The player finds an opponent for which gets a lot of trophies (such as 24 trophies). Attacks, and just losing the battle in time. As a result, he gets a portion of the spoils (eg, 15 trophies instead of 24), and can continue to attack the hero a few times.
I have since lost 200 cups per hour, and it’s one of the enemy! I know, because Olympus was returned only one hero, despite the fact that before this I was also attacked. I got 54 -200 and crystal goblets. This clearly plums.
