I agree that removing GDI protection from a country after hitting 5 hits is way too many. GDI should only protect those players that are not aggressive and who do don't run farms. Any country that hits another country 2 or more times deserves to be suicided on (you have to give something to those players who play the game only to suicide on others or who kill countries for fun). Anyways, the unwritten and accepted rule is that if you lg a country 2 or more times, he/she has sufficient reason to suicide you.

The only difference would be that instead of allowing the country that got attacked to do special attacks, you open the offensive country to everyone who has nothing to lose and wants to get even at someone. It will give a place to everyone.

People that like to police for others would be able to identify the suiciders and help maintain order in the game.
