It's an idea on how to reduce burst from Shiv while maintaining the waveclear.
Arguably the waveclear is still too strong, especially if it randomly crits. But this seems like a fairly quick change to nerf Shiv while maintaining its intended niche as waveclear item.
Then there would hardly be a point to taking it over something like Runaan's that's the issue.
If they made it stronger on nearby targets then, I could see how it would be useful.
some people do get it for the burst and wouldn't give a damn if the waveclear was removed lol
Or they could just appropriately increase the cost. Currently, this item supplements Infinity Edge, gives attack speed, crit, movement speed, wave clear, AND burst. There's no reason it should be 2,600 gold.
