A way to balance Gragas

Yet again, Riot buffed a meta champion, realized it was strong even before the buff and decided to revert it. First it was Zed's base attack speed, now it's Gnar and Gragas. Earlier this season, in 7.2. patch Riot buffed Gragas' passive and base armor) in order to match then op Rengar, Lee Sin and Kha Zix. What they failed to realize is that assassins work only when their numbers are right, while CC champs always work due to more and more CC heavy champs available (please stop making these, CC creep is abundantly high). What ended up happening were nerfs to these ad assassins while Gragas was already the undisputed king of jungle in terms of not dealing with op champs (not to say perfect balance as Gragas himself has op design). NowRiot are reverting armor buff to Gragas (rightfully so) only to realize the buff wasn't needed in the first place i.e. you had issues with other op jungle champs.

My advice is to start looking at fundamentals, that is why is something not strong, and if the state of the champion is bad due to other champs being op, or the champ itself underpowered. When the buffs to Gnar and Gragas are reverted. I hope they start balancing in this manner. Not only that, Gragas himself has the most overloaded kit in the game - passive HP regen, ranged AOE 2 sec slow, AOE aa, E dash that is AOE knockup as well as escape, 1000 range AOE pull+push on R (the single strongest spell in the game). Galio comes close to this kit, but that's it, all other have way less reliability and versatility in their kits. That being said, if Galio cannot dash over wall (and he has wings), there is no way the fattest champion in all Runeterra should be able to do so. Once you make this kind of change, i.e. a nerf to Gragas' utility, only then are you going to solve his undisputed ruledom over jungle.
