I feel like the biggest issue with Shiv is its insane waveclear potential which I don't think is addressed with the upcoming changes.
Waveclear is Shiv's identity (and it's a pretty satisfying one). Items are meant to be strong at a specific thing and that may be frustrating for some, but it's part of the item's power budget and we intend to balance the item around it.
Granted, when the waveclear is too powerful, such that you're one tapping the casters at range, then yeah that can lead to stalling and lower interaction, but we intend to tune the item around that property.
We also intend to allow AP users to buy it sometimes as a bridge to AP AS builds (like Nashors).
