Spectral Blades: How are its PVE numbers so bad

In honor of sword week, I have been running Spectral Blades for the vibes and this super is BAD. I really noticed it in the Grandmaster. I did not do hard testing on it but this is what I was noticing.

It is void burn so I am getting increased void damage. I was doing a whopping 8,000 damage per light attack and about in the 10,000 for a heavy attack (which was not enough to kill a red health legionary). When weakened (with the seasonal perk for increased void damage with weakened), the damage was in the 10,000 for light and 12,000 for light. On top of all this, the lunge on the light and heavy attacks with the poor hit registration makes you clip through enemies a lot of the time, which makes it hard to land more than 1 or 2 hits in a row. On destiny compendium, Spectral blades base damage is 277 and heavy is 405. Bladefury is what I would consider a comparable super PVE-damage-wise and its base damage is 851 on light attack. Im not sure how the scaling works for different abilities but I feel like there are normal abilities and special weapons that do more damage than Spectral Blades.

For comparison, my black talons projectiles were doing like 19,000 damage and my friends arc staff heavy attack (with no void burn) they said was doing around 38,000 damage.

Also, looking at destiny compendium, it apparently drains super energy faster when not invisible which is silly for a PVE standpoint. Its light attack also uses more energy than the light attacks of arc staff or bladefury which is why it feels sooooo short, especially considering light attacks increase your attack speed. On top of all this, it is the longest cooldown super of hunters void supers.

Honestly, it is what is it is, but considering spectral blades has gotten 2 damage buffs in the last couple year, I truly dont understand how it does this little damage. It has been atrocious as far as I can remember. Increasing the base damage to at least the other supers would be a very simple fix to at least make it USEABLE. It still has a number of other issues like the energy consumption and lack of utility. I was using it with void surge and the seasonal perk so this should have been its peak, but it really is a bad ability
