Least used weapons in the game (my personal list)

Through the game I noticed that some of the weapons are not used at all or are extremely rear to see someone using or get killed by such weapon).

For TR I personaly nearly never saw anyone using SABR-13 or the M6 Onslaught (I understand why SABR-13 is so non common, just because it is a burst weapon but the Onslaught?). If talking about secondaries I nearly never saw anything NS revolvers, or TX1 Repeater. I am probably pretty wrong, but that is from my personal observations. About LMGs for TR and NC, the S variants f the standart guns is pretty underused.

For NC the EM1 is very underused as EM 6, (I personaly was not killed really often by it), the AF-8 RailJack, and most secondaries exept stock and LA3 Desperado)

For VS, again, most of the secondaries exept beamer, the Phaseshift VX-S.

And also pretty common thing for all the factions are nearly no use of burst weapons.

Again, it is my personal opinion so if you have your personal opinion, please share it in the comments.
