It is an east gun to use. It takes minimal effort, vex hits 41 per headshot. That is a 5 headshot kill. Also if you look at my medals I have quite a few "the best around" because I focus on gaining points rather than try to preserve my "previous kd" that everyone seems to worship. The vex has a large overall range but a specific range it is almost unbeatable at. So when there's a team of Vex users they sit in that range. So if I pull out mine I can usually outgun them. All my Fusion Rifle kills are with the vex. I despise fusion rifles overall for PvE and PvP. Grimiore should show I have a vex.
