Honestly posts like this scream, "I don't have a good AR!" I played a lot of trials this weekend. Grinded Flawless Pool solo for hours Monday for more Adept SMGs and rank ups. I countered the Immortal successfully, repeatedly, with a fusion rifle, a shotgun, ARs like Rufus's from the new raid, an Adept Summoner, a normal Summoner, a Gnawing Hunger.... They're easy to counter if you try. And that includes not holding forward, but actually backing away and maintaining YOUR preferred distance and range. You know they'll be trying to get close. Play accordingly.
