I wouldn't say 'easily' shoot your enemies. Fortunately, knights can still run quickly with their shields up. Holding right click should not counter a class. I dont need to light things from a distance, my knight can easily get to their base and destroy he whole thing in a matter of 3 seconds. No because builders are the only defense. They are also the coolest aspect of this game imo. Without them this would be a lesser Awesomenauts.
