The system is literally based on whichever clan wars the most.
Yes, that is being strong.
Clans don't make the effort to war because there isn't really nothing to compete for, what do you win being rank 1 ? nothing, so why would people bother.
Unfortunately, being rank 1 is not attractive nowadays.
So my suggestion was to include a totally new clan ranking system. I was thinking that maybe the new ranking list is based on which clan is the most active, has the most members or more broadly, the clan that has reached most of their goals set on their forum page.
That doesn't make sense, the rank is based on the strongest clan and which wars a lot, changing it to the most active clan ? which has the most members ? please, no.
It should have some rewards by being rank 1, it would be more competitive, the rank 1 would have to fight to maintain their top position and the rewards, take the ranking for player for e.g, people fight because they know if they get rank 1 they would receive tcs as a reward.
In sum, i think you should organise more your idea, it's a good thing bringing up the clan's ranking.
