if a clan could only fight one war a day wouldn't that prevent a counter attack though? to allow a clan to only engage in one war a day would still leave the clan open to have another clan have a pending war with them.
i like the idea i just also like to play devils advocate. "only through fire are things of value made".
how about deleting the formal war block altogether? meaning that that a clan could still be ambushed if they have a pending war?
