You do realize that with Don't touch me, I can go invisible when I get hit, which makes it even more viable for me to go down into the fray. I can literally make myself always invisible. With specific gear equipped, I can also have 100% melee cooldown which allows me to use Blink Strike for invisibility very often. I used this invisibility build specifically for PvE because it practically makes me untouchable. And since I do this with a fireteam, things become even easier when I have a Defender on my fireteam. Really, with a good fireteam, most of the phases are very easy, and some are solo-able.
