Gragas Support?
Hey there, Master Fledgling here.
With the advent of Cinderhulk, I am testing and retesting Jungle Cow. But more on that later.
For now, I know that Gragas jungle works and works well. He's also one of my favorite champs to play because he's just goofy and really strong. With just a ROA, he does noticeable damage. And if you build him full mage, he has surprising burst. Additionally, no other champ has offered me just escapes as Gragas has. Wall jumps, slows, bush checks, damage reduction, an amazing ultimate ... I digress.
How might he fair as a support? He has build in damage with W, good lane sustain, a stun (more as a peel I figure) and is naturally tanky. His ultimate also would be grand for peel and initiating/making picks.
Let me know what you think and don't play any drinking games with Graggy,

. If they jump on your markman, belly flop them off for a disengage. Once you hit level 6, you basically have a
ult and all the (dis)engage power that brings as well. Your sustain and tankiness are decent, and you have poke too.
