A class is a light class which dosnt carry heavy weapons. They carry the same ones as the heavys do. So if you think its ok, then do you realy think that an A class compaired to a heavy can carry the same amount of ammo? No A's are faster so they dont need the heavy weapons. In 6 months time everyone will only be using lights for that reason. It just dosnt make any scents to me. Hell all the A classes are taking the heavy classes over on the frount lines. Is soo un balanced.
I would suggest since they can move faster and dodge faster and get away they should be using a less damage weapon because they can hit a heavy twice as many times. it only evens it out.
