It's a position that makes sense. I just played a guy who scored 5400. All shotgun kills. (He sucked - think I went 10-1 against him 1v1, scored 6500 myself). The problem is these weapons, with a constant flow of ammo become a crutch. I admit, I used to always have a shotty as a backup to my HC. I'm now running VoC and light/beware and even on the bigger maps, my fusion accounts for probably 70% of my kills (and nearly all streaks, as dumbasses charge my bubble endlessly).
