Well you see Lowe I'm playing Gold
In any case, whenever I join a lobby and I get the feeling that the team is crappy I go immediately for the Juggernaught as I've gotten used to it that I literally am able to carry a team through.
With a Particle Rifle and the Reegar shotgun I never die. My team was so bad that I had a medal for 20+ revives....that's how bad it was but we still extracted because even after everyone was dead I was able to take the mooks down easily. When my health got low my turret would provide that last minute boost plus the melee healing.
Though I can't argue against the Hex shield but it's just not me.
And since your using the Hex Shield you must've seen some issues with scions. I swear their shots are able to penetrate the shield I'm not sure if it's intentional or a bug.
