Weapons & Equip Influx Waver should get the 1.4.4 slash effect.

That's it really, it feels like an odd omission since its in a similar place to terra blade and horeseman's blade, feels like it would make the weapon feel more powerful even if it doesn't have any stat changes.
Here's a demonstration that i shoddily edited together using the sprites

I agree it could use a visual buff. I might vote for something a little more unique, something electric-y and fitting with the alien nature of the Martian Madness weapons, but the point still stands, Influx Waver got left behind when the Melee changes rolled out.

Honestly I think every sword needs an aura, for both visuals and functionality. Most of the current swords are extremely bland and boring. Not only that, but swords with Aura have a property that makes them always swing towards the cursor rather than the direction you are/were facing, which I think is sorely needed for a sword to be useable.

Your right it should do that and the knife projectile size should change or be doubled in size
