High defense players have no more reason to join now as there is no score for staying 3-4h in defense mode after a few hundred attacks. I think there is no more reason either to buy high defense limited to have a longer defense time, maybe once every half a year when they get better with at least 10%. If you will resurect, it will be better to load your best attack weapons to make bigger damage and click as fast as you can until they find you. When they find you, from 20-30 clicks you are dead with your low health and you loose one more third from your score. I doubt that you will have time to react and go for defense mode. The only moment worth to resurect will be the last minute before the last day, as the last day you wont loose more score when you die for the last time.
