If you use the boltshot and AC combo, only throw plasma grenades and hope to get a kill, use rockets, incineration cannon, or fuel rod cannon at ridiculously close range, use camping to win games(especially in ridiculous and almost impossible to reach spots in any infection gametype), go for a melee before shooting your opponent, betray teammates for weapons or vehicles and die immediately after getting them, don’t know how to switch between the guns on the banshee, can’t get a kill within 5 bullets(precision loadout weapons only), try and take on a mantis or other large vehicle on your own with no power weapons, or kill yourself with your own ordinance.
So using boltshot means you are a noob? Go ahead and tell all the weapon masters how noob they are for using it. My sidearm most of the time was boltshot when I wanted to master it.
Most of the people just judge anyone who they see as a noob the moment they see him/her use the boltshot and don’t realize they are trying to get kills as fast as they can with it so they don’t need to use it anymore.
