On Android you only lose stamina. That's not what I call a punishment. And I have plenty of Def, but that doesn't help much when people 20k under me can attack me...Yes I could just collect in time (which I usually do) but that doens't make it right. I have a feeling that you're one the idiots exploiting this "feature" and don't want to see it gone.
Anyways. Sorry for coming here with a suggestion, I guess this game is perfect in any way...
