I don't know if this is by design or a bug.

Serpent strike with a sword with a hunter fires the Maran weapon extra fire attack.

Serpent strike with any other weapon, staff, spear, dagger, whip, do not prog it, ever. I am making an assumption axe would fire it, but hunters don't know axe so cannot confirm.

This is strange and wanted to ask about it to see if they should be brought in line or if its a rogue piece of code for serpent strikes with non-normal ranger weapons.
