Usually the battle, players from picture look BOSS, feeling them in the attack at the time did not fight appearance, because they just stood there, sloshing around, this will let us have a relax fight state of mind. But the mood is usually let us eat a lot of losses, monster though beautiful appearance, but please don't ignore it AI degrees.
In the game despite a lot of BOSS is the "tank" level, but it will kill you, so you have to good mastering all skills, because everyone is not willing to hang at key moments. Remember and a BOSS levels of the dragon fighting, let it in 50 within range will kill me directly. Last may have many wall map scene, so the second time after the resurrection by using these natural barrier slowly it as a kite flying form to kill.
Finally, the need to explain is turret is your best friend, because it can be effective to attract the attention of all kinds of BOSS.
"The guild wars 2" use different skills and changing BOSS fight, let me feel very happy, but regret is not to see other two BOSS (shadow behemoths and the destroyer).
