Arum Spinosa (possibly Quassus) heavy attack issue

[ArdonN7]

The Arum Spinosa warfan (and possibly the Quassus) heavy attack seems bugged. Testing shows that the weapon's heavy attack hitbox (the weapon itself, not the projectiles) do not respect equipped range mods, or perhaps the animation hitbox for both heavy attacks are broken.

The third warfan, the Gunsen does not exhibit this issue as the heavy attack lands in the supposed range and width, while the Arum's lands at roughly 1/5th of the range (almost enemy touching distance instead of 4-5 meters). Also, the animation seems to keep a roughly 3-4 meters range at the sides and back of the warframe, but only in a minimal angle.(15 degrees behind left and right elbow, further testing required?)

This heavily effects the performance of the weapon, as both warfan stances heavy attacks are considered very effective, and this issue makes this close-range option nearly unusuable.

Furthermore, some unconfirmed sources suggest that the Arum Spinosa heavy attack projectiles should be(?) forcing either a Toxin or Slash status effect on the targets hit, but this is definietly not the case as of now.

Thank you.
