For me it depends upon the map, but I find myself using Lingering Song more in Supremacy. The greater per-bullet critical damage versus the Hawkmoon archetype will also allow you to 1 headshot + base melee kill even a Ram Warlock without LiTC proc'ing. With reinforced barrel it also has superior effective range when you need to help out a teammate at a distance. Admittedly I haven't paid enough attention to see if the 1 (non-LiTC) headshot + base melee kill on a Ram Warlock is possible with the 81 impact archetype currently, but prior to the armor tier and Ram adjustment it wasn't. If it is possible now I may dust off the Hawkmoon on close-quarters maps. Good hunting out there, in any case. :)
