Respawns must be removed from attack and defend to make this gametype tactical. Attack and defend is best when round based.
In attack and defend each team "spawns" at opposite sides of the map, and proceeds to pursue its objective. Because this is a scenario gametype usally with 6+ players 3 per team when a character dies, the player must wait for the next round to resume play.
In a room created by the host he or she must have the option for round based play such as the number of rounds, round type, and round time.
