Always on time from the exotic vendor in the tower. The "less aggressive enemies" perk doesnt actually reduce how often enemies attack you(I think that would be really complicated to code) so Bungie just gave it -blam!- tons more HP than every other sparrow in the game. Feels like D1 sparrows imo, also its the only sparrow in the game thats 190 or 200 speed due to a bug thats never been patched and I hope is never patched and instead they increase all sparrow speed. Which is sad bc its the objectively best sparrow in the game and I havent swapped off since I got it.
