A Titan killing 3 people with one hammer is very situational too. It won't happen often. Nightstalker has the perk where damage is shared between all tethered targets. If you ask me, that seems like the most OP thing in the new subclasses. Shoot one arrow, it tethers 3 or 4 people, you shotgun one and they all die. They can't even run away and Shadowshot has a pretty large radius. It's basically a free multi kill if you Shadowshot into an unsuspecting crowd.
