If you want to drop cups please use a defence team with 5 heroes and not one with one strong or weak hero.
It is in your own interest and would be a sign of common courtesy.
If I see an understrength defence team when raiding I reroll because to fight it would be a waste of valuable raiding time. I prefer to have a chance to collect 5 heroes for my chest and not only one.
I am sure I am not the only one with this thought so use a full strength team please.
