I think your Clan rank should decide how high you are in the coalition charts.
This is a suggestion when options get added for Clan versus Clan battles.
Basically you start with amount of points 1,000. If you win against somebody higher than you, you get extra points. If you win against somebody lower than you, you get only some points.
When you lose against somebody lower than you, you lose extra points and when you lose against somebody higher than you, you only lose some.
The more points you have, the higher your ranking.
