This gonna make me sound like an a hole but it's the truth . If you can't and know you can't get positive kds in the crucible then please stop playing it . You ruin the experience for people who actually play to win and care about being good. Also if you are good at the crucible but it's because you use a vex and a shot gun then you aren't any good and you as well should stop playing. untill you know how to use the games talented weapons and know how to play without relying on the games best over powered guns to do the work for you .
