As a Gragas Main who always loved his AP Bruiser I am in love with those buffs
Gragas [Context] Explosive Cask (Q) AP ratio increased from 60% to 70%
Drunken Rage (W) AP Ratio increased from 30% to 50% [New Effect] damage reduction is now increased by an additional 8% for every 100 AP.
Real Gragas Mains always played Gragas AP they never liked his Tank Vanguard type because it doesn't require though on spamming abilities while AP Gragas has to think how barrels are setup and are afraid to go in knowing they won't survive, I would put Gragas more like a Diver Assassins just like Diana which he excel at hit and run type of dueling.
Gragas might be a champion that has everything a Tank wants but his core design was never meant to be a true Tank. He is a Bruiser, a Brawler kind of champion, It's just like Diana, yes you can build Diana as a Tank but you feel that if you built ap you would actually be dependant on yourself and not on teamates Damage.
I know those buffs are experimental but PLEASE KEEP them, I'm updating my PBE account just soo I could get to play GRAGAS as a Mid laner and not a no brain Jungler.
