How Graves should be changed for the current jungle

I'm a pretty low rank, but I think I have a good grasp on Grave's strengths and weaknesses, so here are some changes I suggest.

The jungle xp, dark harvest, and stormrazor nerfs hit him hard. His Q is probably the best thing in his kit other than the blind, and really doesn't need the buff you guys are giving him next patch (although it's appreciated).

I would suggest giving his ult more damage, maybe even make it an execute. There are many other ults in the game that are long range damage ults like his, yet they do more damage and often have some other affect along with them (karthus ult does more damage, is not a skillshot, and hits everyone).

His E stacks should also last 3-4 times longer, as they are hard to stack anytime other than when he is clearing the jungle, and are pretty useless in most fights unless they last a very long time, which they don't in the current meta.

Finally I would suggest giving his auto damage some sort of buff, especially early on. Graves autos don't feel like they do much compared to other junglers (Like Kindred), and really only start feeling strong at 2-3 items.

His Q and W feel good as they are, and really don't need changes.

Some or all of these changes would not only make Graves feel good and balanced in the jungle again, but it would also sell a lot of his new skin, making Riot more money, which I know they like.

p.s. Please add canceling the R knockback with E back :)
