Gragas Buff please.

I personally think Gragas is a little sub-par right now. Everytime he gets picked he always loses and he has no mobility and damage. I think a buff to his w would be a great buff say make it to 24% of missing health and make him take less damage until the duration is finished. Also, a buff to his tankiness wouldnt hurt either because hes a little underwhelming with cinderhulk compared to most tanks and a buff to his R range wouldn't hurt. That's all thank you for reading this i hope to see his buffs in the next patch cycle thank you.
