thing is if something is destroyed it is destoryed, if it is not is is not...
So achieving the mapgoal in a certain time has a bigger influence on the war map and so on. Or
winning the map but destroying the "important bridge" gets you more or less nothing on the war map.
except the territory sector...
. (unless your defending)
also i dont think it is fair to trap players in an area by destroying bridges, it would be easier to inpliment if the destroyed bridges jacked up deployment times.
