If you're low on etheric light and want to get one good all around sniper, I'd go for Her Benevolence with shortgaze, clown cartridge, casket mag, and if you get those 3 just let the final perk be whatever. You will have decent but not super high aim assist (better than either efrideets or praedyths with that roll), very good impact, and the combo of cc + casket mag gives you the highest ammo setup you can get, and more shots = more chances at damage. For casual PvP you don't need an ascended praedyths for a OHK head shot or two body shot kill on anything but a Goat Hat Warlock w max armor or anyone w a shield or in their super. The new efrideets really has zero to offer over a her benevolence. HB is all around more versatile, and the slight impact reduction is nearly meaningless.
