The defender is criminally underrated, it's been my go-to on bugs combined with light armor and the ARC thrower since I got the game pre-railgun nerf. Everyone complains about the hunters but I never seem to have issues just running away and hip firing behind me
There is a downside though and that's the red dot. It has no scope like the liberator has so sniping is not as easy and accurate because no zoom scope available. For a smg the fire rate is also pretty low but it makes up in damage. Kind of strange it hits harder than assault rifle but has slower fire rate.
This Video was a great analysis of the Defender. One of my favorite guns in the game and I love it with the Ballistic Shield. I hope you do more videos. Good Hunting.
Both SMGs are indeed very strong. I disagree with your assessments of other weapons however. There's no way you had ammo issues with the breaker before the ammo nerf for example. That's just silly.
Sorry I was more noob , and played maximum on 7 difficulty, but soon there will be jar 5 dominator review with bunch 9 level difficulty clips. I hope you will like it.
