You mentioned a slight buff to Nightstalkers, which I personally think needs to be a faster tether speed. Other than that, they're golden...um, I mean purple? Whatever, you get what I mean. The tether just needs to activate faster, a lot of time I shoot the arrow, get shot several times, then the tether activates. Now usually I survive getting shot once or twice, but with a hammer, one throw is all they need, and while I can and usually do shutdown their super, I usually die as well (Super being HoS and sometimes Stormtrance)
