Is the Scylla IG any good? I've been using Gore's for what feels like forever. It's either that or I got for the Scylla CB.
Nerscylla and Gore IGs are pretty much the only ones worth using in all of LR and most of HR. Gore has some nasty material requirements at some point (plate, gem, two different mantles) but has dragon damage which comes very in handy as a lot of monsters in HR are weak to it. Nerscylla has the advantage of having fairly cheap materials and native purple sharpness at max rank. Unless you got really lucky with your Gore drops I'd say craft and upgrade the Nerscylla glaive.
