AN IDEA ON HOW TO IMPROVE REWORKED GRAVES NEW PASSIVE

It seems that on the boards everyone is kind of upset or wondering how they are going to cs as Graves with the new passive. I had an idea that might fix this problem. How about when Graves kills, or last hits a unit he automatically gains another shell in his shotgun without having to reload. Another idea i had is increasing the amount of shells he can store as he levels up as currently he can only store 2 at a time. Any input would be great thank you for reading.
