Volibear Passive Values and Irelia/Nasus "Bug"?

I was wondering that with the recent changes to other champions ( Garen, Mundo, Gragas, etc.) who have ability properties like Voli's passive: (When Volibear's health drops below 30% of his maximum health, he will heal for 30% of his maximum health over the next 6 seconds) can we change the % value to the actual value in the tooltip?

It would make things easier visually to know how much HP Volibear is going to regenerate overall and per second rather than just the arbitrary HP%.

For the Irelia/Nasus "bug", I've noticed that when I use my Q at close range with Irelia that is sometimes goes on CD on minion kill OR the minion dies, my Q resets, and I get no gold. I'm not sure what's causing that exactly, and I haven't played Irelia in a few weeks due to me grinding to get to Gold rank again. When I can, I'll record and link some gameplay highlighting the interaction with it as it pretty much has happened multiple times in every game I've played as her.

The Nasus bug occurs when Nasus is mid AA with it being empowered by the Q. If the minion dies mid AA, the Q goes on CD. It possibly could be because my damage wasn't enough to kill the minion and would have left it with 1 HP and a friendly minion finished the kill, but visually, it appears that it dies before my Q hits and sets it on CD.

Thank you for the consideration with this,
