Defense bonus, if the attack was fought of without triggering a shield

Didn't find this through search or in the blocked requests.

Getting attacked alot gets a litle expensive if you have to reactivate your traps, x-bows, and infernos all the time.
I find it fair if a player recieves a small bonus if he or she successfully defeated against an attack that did not trigger a shield.

The bonus should represent at least the amount to reactivate all triggerd trapps, x-bows, and infernos.
anything above is nice to have but not a must.

Thanks for listening
