Isn't it About Time to Buff Gragas?

This dude is in a pathetic state, his win rate is consistently around 45%, one of the lowest in the game. Between the nerfs to both Cinderhulk, gromp buff, and targeted nerfs at his kit (slow on Q, width of Body Slam, passive nerf, etc) he is a mess. He doesn't do damage, he doesn't really tank, he just offers some CC and a knockback and then prays to the elder gods that his team will do the rest.

Here are some suggestions.

1 Tweak his Q: Currently every single thing on his Q (Barrel Roll) scales with how long the cask "ferments"...the damage, the slow duration, the slow amount, all of it. Give Grag at least one thing for free, one thing that doesn't scale it just happens. For instance, the slow duration should be 2 seconds flat, not a scaling from 1.3 to 2 seconds. Because the the slow amount is scaling, isn't that punishment enough for not letting the cask sit? The slow has to wear off faster as well? Grag is simply too punished for insta-popping his cask, which honestly takes some skill to pull of when so many champions can just jump away as soon as they see a barrel rolling at them, hell, skill players can sometimes just walk to the side to avoid it.

2 Give him some damage: His damage early is pretty decent, but after a while it's a complete joke. There are tanks in this game that do way more damage than Grag, and Grag isn't even a real tank, more of an AP fighter, so why is his damage so crazy low?

3 Revert passive nerf. Seriously. There are plenty of champions who can sustain WAYYYY better than Grag in the jungle, if those champions are fine then Grag should be fine to get his passive buffed a little so he can actually stay out a bit longer. I mean I'm already going back to base all the to get mana because yall removed mana pots, why should I have to go back all the time for health as well? His clear is so bad right now it's Kha'zix levels of getting my ass beat in the jungle and having to back every other second.

Those are just a few suggestions, but the bottom line is Gragas needs some serious buffs to become not even a top tier jungler, but at least a competitive one.
