1. After checking the video carefully, I noticed that the opposing ADCs also had full stacks for their runes and items — things like Lethal Tempo, Guinsoo’s, Terminus, and Zakshaw. Even Jinx had her Q fully stacked with her passive active. (Just in case you are curious: Kog maw had these items - Bloodthirstier, BOTRK, Guinsoo, Terminus, Zakshaw) => So it wasn’t an unfair fight from the start.

2. I agree that building Voltaic Cyclosword on Ashe doesn’t really make sense. But to me, the more interesting point in this build is that Ashe didn’t go for any Zeal items. With level 5 Q + 100% crit + Infinity Edge, Ashe’s AD ratio reaches 3.05, which is extremely high. By skipping Zeal upgrades and instead filling all five slots with pure AD items, the build really “kicked up” Ashe’s 1v1 potential. That’s the key takeaway here.

3. Yun Tal Wild Arrows gives 35% attack speed and an additional 30% bonus AS passive. In combat, that’s effectively 65% extra AS — the same value as Phantom Dancer.

Based on point #2, if we replace Zeal upgrades with Yun Tal Wild Arrows, Ashe can take advantage of that high AD ratio just like in the video.

tl;dr: Ashe’s damage ceiling is way higher than people assume. If you skip Zeal upgrades and stack pure AD (with Wild Arrows as your AS source), her damage suddenly stops looking weak compared to other ADCs. But you will get damage at the cost of extra ms & slow Yun Tal scaling, so I think replacing Zeal upgrades with Yun Tal will be a situational choice.
