CTR DMG ASI MAX Winfinity. Serious idea here, folks.

Name: Winfinity
Combo: Three swings, same lunges, same bullets.
Normal dmg: 84% the DPS of the Leviathan Blade.
Speed: 84% the speed of the Winmillion.
CTR: 116% the charge time of the Winmillion
Statuses: none
ASI, DMG, CTR: MAX
Basically, what I'm pretty sure that equals is a 5* Spur that effectively has a guaranteed Medium UV in each category, but won't accept any more UVs, because you can't go over MAX. Like the Winmillion, it's a sword that starts off okay, but doesn't work effectively as an endgame damage source. It's not overpowered at the endgame, and Spur users get their Winfinity.
(I'm basing the numbers off the assumption I got here that a low UV is 4% of whatever it's controlling, even speed and charge time. If that assumption is incorrect, I'd want to adjust the numbers to whatever makes the sentences above true.)
@"Winfinity has been suggested Winmillions of times already": Great, find me a thread with reasons why this specific Winfinity won't work, and I'll send this to the graveyard for the zombies to read. I haven't checked, since there are so many threads, but I somewhat doubt anyone will have thought of this.

There's got to be more to discuss...

So why would I make this if, as you say, it's still not an effective endgame damage source? If I'm not going for damage anyway, I might as well stay with Winmillion or just get a gun.

Are the original statistics considering it's own max DMG ASI CTR or do those apply after that.

The percentages up there weren't including the UV; the ending percentages should be 108%, 108%, and 92%.
It would still be an semi-effective damage source, better than the Leviathan Blade and Cobalt gear, but I'm considering endgame damage as something that wipes out small crowds in only a couple seconds. For example, the Brandish-Chaos combo.
...actually, I suppose "maximized" would probably be a better word for what I meant.

BAHAHAHAHAHHAHAHA!
When I first read "Winfinity," the five star Winmillion idea popped into my head already. But, I think you might have a nice idea here, but the purpose of Spur is gun-sword. That's why(I think) it stopped at four star, because it would hit Max then and the gun-sword purpose will still be put in.
In any way, +0.5
