3. The Combat Engine
The combat in WOW is somewhat stiff and based on the aging tab-targeting system, which can be clumsy and time consuming when fighting a horde of monsters. While the combat mechanics in Guild Wars 2 aren't quite as smooth as they are in Tera (another recent addition to the MMO market), you can attack on the fly, hit numerous enemies and use special dodge moves, making the combat in Guild Wars 2 much more fluid, dynamic and exciting.
