Because i've tryed the faction NC and tryed the medic and infiltrator,but i cant kill a lot caused i select medic for do certs and infiltrator for try,and i fail,but my favorite class was always light assault of vanu,and i dont try again the rifle burst. Now i go with light assault and this time i wait for a 250 certs weapon,and there are 2 to select,Pulsar C that i think have more firepower and Serpent VE92 that have more rate of fire,im thinking to buy Serpent caused that in tutorial said that pulsar c the weapon aim up when u fire continued and i prefer aim to firepower. And in the game said that the Serpent have fire rate high and i think that is similar to GR-22. But between a weapon of firepower of nc and rate of fire of vanu,in close quarters,who win? Aiming correctly of course.
