How would Garen's new E interact with cripples (attack speed slows)?

"8 + 1 per 12.5% attack speed"

"applies on hit effects to the nearest enemy"

Since every spin from his E counts as a practical basic attack on PBE, (due to its behavior to trigger on-hit effects) would Garen have less spins than normal if he was crippled? This made me really curious. Potential video idea for Vandiril? Upvote so he can see this.

Let's put it in this scenario.

Put Garen against Malphite, Fiora, Nasus, and other champions that will build Frozen Heart. Since Garen E scales off attack speed, I wanted to see if its possible to get no spins at all or at the least very few spins for the full duration. By the way, it's essential for Garen to be Level 1 or else he'd be gaining bonus AS from base stats from leveling up. Malphite, Fiora, and Nasus should all use their cripples all at the same time and Garen should immediately press E for maximum effect, what is the interaction here?

Here are the stats:

Malphite E slows AS by 50%

Fiora W slows by 50%

Nasus W over the duration decreases AS all the way down to 47.5% to the last tick

Frozen Heart reduces AS by 15%

To sum up, all of these combined would reduce Garen's attack speed by realistically 150% (depending on Nasus wither). You can do the math here for how his spins calculate to his AS.
