Yes I am a hypocrite. But you tend to be about things ya spend 1000s of hours using... I have tried most builds that there are for Zephyr. Even full umbral for good fun. but no. there is still no point in building specifically for her passive. If you want to for that one riven challenge sure. but aimglide is not a viable build. but hey each to their own!
It has a shitty critical chance, but with all critical mods and with multishot, it gets a little frequent; and then, with 5.6x critical multiplier, and 100% bullets to the head, it really gets interesting.
Now add punch thru to hit said enemy behind cover, or even multiple enemies.
