No, it isn't ridiculous. Strategy is needed to win in Clan Wars. Especially if the opposing clan has about the same number of people left as yours, hiding might be a good strategy as your clan can finish them off one by one as they fall into your hiding place. Clan Wars is supposed to be flexible enough to allow you to fight within an area which you can find any enemy inside with enough time, so long as you keep finding. Thus, as I prefer to fight out-front, I neither support nor oppose hiding.
