I think that Gragas will need some nerfs in the near future.

Gragas currently is in very healthy spot, probably the healthiest since forever (S1 and S2 he was considered a joke not a champion, in S3 and S4 he was top tier midlaner, in S5 he had nearly 70% ban rate and for first half of S6 he was top tier jungler). And now statistics from various sites show us that he is in sweet spot atm. Here are some stats to prove my claim:

Lolalytics shows that he has 50.07% win rate with 6.69% pick rate in the Jungle and on the Top he has 48.44% with 5% pick rate. His overall ban rate is 1.73%. Slightly different data is on op.gg as he has 49.33% win rate and 4.79% pick rate in the Jungle and on the Top he has 49.22% win rate with 4.58% pick rate. Overall ban rate is 0.53%. Still counts as very healthy.

Recently I saw some posts about Tanks performance in the Top lane post MYTU (Mid Year Tank Update), most of them dropped in win rate and Fatman was one of them. Then we received post from Meddler who stated that those Tanks who started to drop in performance due to Sunfire changes will get compsensation buffs. I honestly think that it will be bad idea to buff Gragas directly because he already is in perfect spot in the Jungle (his main role and he was even balanced around this role for a long time). Any serious love taps to his stats for the Top lane will benefit Jungle Grag greatly and it might break him once again.

You might think that the solution is to not touch him at all and that my title has no sense so here comes another argument. We are receiving Lee Sin, Graves and Ivern nerfs on the PBE and those three are one of the biggest antagonists of Jungle Grag so his rise in winrate is imminent and I think that for this reason alone he will need to be looked at. When he will get those indirect buffs combined with the direct buffs due to his drop in performance on Top it is very likely that we will get another season of P/B Gragas in the pro play and this time might even break Solo Q at the same time (in S6 he had from 46% to 48% win rate in Solo Q while being top tier in pro play alongside Rek'Sai and now in Solo Q he is very close to 50% win rate).

Fatty is my favorite champion, I started to play LoL just because of him back in the preseason 2 and have mained him since then. It would really suck to see him in disgusting state once more when he is so close finally to being OK, to not be able to play him because of bans or constant picks and to see growing hatred against him. I beg you guys at Riot to look at the "whole picture" before deciding to buff him. Or maybe I'm exaggerating things and those changes won't be so bad? But either way it's better to be sure, after all it's better to prevent than cure, right?

I'm afraid that due to my love bias towards his current state and not the best game knowledge my feedback on this topic won't be helpful so I trust in you guys. Current Gragas is very fun to play (funnier than ever even though I have nostalgia for the old times of this game) and he is balanced, healthy at the same time (I mean gameplay wise because him being so fat and drinking that much alcohol probably ruins his health) and I'm sure you'll manage to keep him that way.

I'm sorry for my bad English and terrible writing skills, I hope that it wasn't as painful to read as I think it is.
