Yes. I use the way of the thousand cuts. Will take a boss shield with one super, grenade, and throwing knives. It then takes about four supers to melt the boss. The mode offers constant supers so no need to wear things just to get super energy. Being you only have a Titan up to level, I would run hammers for great range and ad clearing. You do need speed due to the fact you can run out of time. I have not been able to solo tier 3 yet because I run out of time, not because of getting killed.. The risk runner is good for massive ad control. Rampage and outlaw on a kinetic and, do not laugh, but the edge transit for major boss damage will get you there.
