There's currently a bug with the Polaris Lance exotic scout rifle bug where Perfect Fifth kills only count towards the catalyst's progression if an enemy specifically dies from the DoT burn. > Directly killing an enemy with a Perfect Fifth loaded shot doesn't count. > Killing an enemy through the shot's AoE explosion doesn't count. > Only a kill through burning to death counts. This is particularly irritating as the burn effect does very little damage compared to a direct hit, meaning an enemy has to survive the explosion while having a SMIDGEN of health left to be successfully killed by it. And situations in the game where that happens are VERY rare. Please could someone at Bungie patch this to make progressing the catalyst actually reasonable? The Lance itself is already an incredibly lacklustre exotic with how much effort is needed to activate it's perk compared to how little playoff you get from it (ESPECIALLY now that other exotics with similar concepts are out, like Trinity Ghoul, Let Monarque, Malfeasance, etc.), but that's a discussion for another day.
