Also, higher rank in HS effects its proc rate which is why HS sucks balls when we first get it. Make sure you max planar power and the expansion specific stat increases because dex will effect rate as well.
As you already know trick shot, haste, a good quiver, and the tempest line/called shots all give more frequency to your shots, thus giving HS a higher chance to proc. A lot of rangers also swap to bow of the destroyer which is a quicker bow to increase rate of fire even further. I personally don't do it because I'm not that hardcore, I like to relax in game and min maxing isn't my thing.
HS really takes off at 81 in PoFire C2. It's amazing AA xp and great plat drops. After C2 I levelled until I could do DSH Minos which weren't nearly as good, but still decent. I skipped FoS entirely and went straight to kaesora library which I love. Its circular and leveled setup is perfect. I also feel it is less populated than feerrott so it allowed me the opportunity to get a ton of AA uninterrupted.
