the fourth star for clan war
Many players create clan with high tech level and town hall level but low deference level, to win the clan war.
I have to say it's not fun because the result is decided in the beginning.
In most case, they use level 11 town hall fight with a 11 town hall or 10 town hall. Normally they can get one more star than competitor.
To repress this behavior and encourage low level player, why not add the fourth star for each battle. It could only be achieved when 100% damage and town hall level is lower than opponent.
