The guide isnt bad but ap gragas is much better...

A good guide overall, and I'm more than happy to +1 this to counter unnecessary troll votes.

I will recommend that you remove the "Story" section, since it adds very little to this guide and takes focus away. In addition, you don't need to describe in words what each skill does when you use the Wikicodes (the double brackets) because anyone reading can just mouse over for a description of what each skill does. No need to add extra words that clutter the guide.

Also, a little bit of proofreading will go a LONG way here. Check the spacing on some of your summoner spells and ability explanations, and try to fix some of the typos. Most common mistake I see is "your" vs. "you're". "Your" indicates ownership. "You're" is a contraction. Typos happen, so I'm not knocking it, but they're floating around. I can find them if you like.

Overall, a good tank build with some decent alternatives. I might recommend some alternative choices to allow for some more damage while still maintaining the tanky nature ( Rylai's Crystal Scepter for example)).

way to tanky to do any damage

Great Build +1

Great build, the first match I played with it I went 6.1.15. Never tried tank Gragas but it owns.
