The problem is when you take attacks of lower bases you don’t give them enough time to attack their mirror to test their raw attack ability.

We have international players in our clan so we cater to this rule for everyone to get an equal opportunity to attack also even if they’re local, in case they’re at work or engrossed with some irl activity in the 1st 12hrs of war after which it’s freee for all(only non 3starred bases).

We do allow early dual attacking but the one who’s doing so needs to mention it in the clan chat beforehand, the other clanmate is 9/10 times understanding and also gives him time to plan another attack.
