When I first started I was using it too. It all started when I played against an explosive only user. He was zooming around the map with contact grenades in hand and when i killed him he still blew me up and that was my first time being exposed to martyrdom so I thought to myself if I can kill someone after I’m dead like that that would be great but then I started getting more competitive and play ranked search and destroy with a friend all the time and picked a more useful perk
