This guide has really good points to it, but a lot of things are kinda missing. I would usually downvote these kind of guides, but your writing style is unique in my opinion. That is why i'm going to upvote it! Update this more, so you'll have more stuff, such as more laning partners and such.

Nice, friendly writing style, nothing groundbreaking but generally all valid notes.

Do you build up dmg quickly enough with Warmog so early? There's always the risk they just ignore you, since you have no taunt or fling.

Could you add a section on how you compare to other off-tanks, such as Cho'Gath etc?

+ Love the screenshots of his ult :)

- Minimal differences between cheat sheet 1 and 2, I recommend just keeping it to one.
- Havoc is really terrible :/
- Could use some columns ^^
- Could use a bit more explanation and in depth.
- match up list should be expanded :)

Those are my tips, I hope you will put them to good use :)
