Blade Vortex of the Scythe - First Impression after bug fix + Feedback

So after checking it appears the damage potential is higher than normal blade vortex, but the exchange is the maintenance casting rate.

The area coverage says 1.1 meters, but feels MUCH larger (i could be wrong tho), I also dont immediately see a radius coverage increase with Replica Karui ward. Is it working correctly? If its not, consider keeping its current bugged aoe but fixing its scaling and stats.

I can only currently see two very good feeling ways to use this gem. Totems or self curse.

Some suggested changes:
- Increase the base duration by 0.3 seconds to a total of 0.9 base duration before quality
- Base duration increase of 0.3 at 20% quality to a total of 1.2 durations when fully qualitied

The above makes some better numerical changes to how it interacts with duration nodes on the tree:

Duration x Increase x More = final Duration
0.9 x 1.45 = 1.305
0.9 x 1.9 x 1.1 = 1.881
1.2 x 1.45 x 1.1 = 1.914
1.2 x 1.9 x 1.1 = 2.508

The values provide fundamentally better reward for investment without (in my opinion) breaking the desired functionality of the design.

Another fun suggestion, since it doesn't scale with number of blades anymore, why not add the Nova tag to allow interaction with Astral Projector? Just a little something I think this would make the skill have an extra extremely cool feature in comparison to its counterpart.
