Can we get some context on the Blade of the Ruined King changes?

For those who are not aware, has some tentative PBE changes that increase the amount of AD and lifesteal on the item, reduce the attack speed, and remove the active percent health steal. Riot is also playing with increasing the movement speed steal to 25% and allowing the player's auto attacks to increase the slow duration up to 4 seconds.

BoRK has traditionally been an item to allow attack speed based champions to shred high-HP targets, with an active that has more traditionally been used as a quick direct damage nuke. What I don't understand is why the item is being changed so that it synergizes less with the passive of 8% current health per hit (less attack speed) for slightly more attack damage. The primary users of this item would prefer to maximize attack speed in their builds just to name a few. Secondly, the item's high cost negatively impacts purchase desire with the removal of the damage nuke. While I understand that this active consumes a lot of the power budget for the item, the PBE changes do not appear to offer enough of an alternative to the current active to warrant outright removing it. Do you have additional tentative changes for this item to supply more power or are you redefining the niche for this item?

Thanks for your time.
