Performance Rewards in Factions

Unlike missions in the original Guild Wars Prophecies campaign, story missions in Factions do not feature bonus mission objectives. Instead, you're awarded between one and three sword icons based on your performance on the mission. In most missions, your performance reward is based on time, but a few missions are based on other goals. (For example, Gyala Hatchery requires you to save Baby Turtles, while Eternal Grove requires you to save Tree Singers.) In every mission, you receive 1,000 XP the first time you complete it. http://www.guildwars.com/gameplay/combat/missionsquests/
