That's exactly how I understood his explanation.
But the reason why I say he should kick some peoples is to balance out the clan war for us playing peoples.
We have like 70 members. But only around 25 playing. So we fight with 25 against clans of 70.
So after a "cleanup" we would get in a division with other clans of around 25.
I agree on the fact new members shouldnt count until the next war.
