Also, after i thought again, the respawn invincibility should be map related, as some maps just need that short invincibility because otherwise they just might get past the efc defenders and kill the efc instantly, what would affect the gameplay severely.
F12 for map related invincibility (yes, it would be a minor map format change, but imo it should be like with the dedicated server: if there is a line xy it would use the number that is there specified, otherwise it would use the default lenght)
Thinkings?
