Well, this is my first guide I've ever built, so feedback would be nice, don't be to harsh. I've played this Renekton build several times before in games, and usually come out with top best 2 scores 7 times out of 10. This is meant to be played top lane. The idea behind this build is to be self sustaining, and stay out as long as you can and make gold!!!!! The life steal stacks nice with your Q and is just amazing on Renekton because he deals massive amounts of damage, thus healing you a-lot. I've one shotted plenty of Sona's, among others, lol. Remeber a good farm is always good for any champ, keep calm and farm on, until you get interupted. After i push first turret if mines not down , I go gank other lanes brutally. Renekton was probably the reason I started playing LoL, just so badass looking.

Pros: You can stay in lane and solo anything other then baron up till level 14. If done right. Godd healthy damage, Lifesteal is great with your Q. Hard to out run with Randuins slow and Zephyr speed boost.

Cons: not very tanky, easier to kill early to mid game. Some late game champs will give you a rough time. Example Viegar, unless you can get to him, then you can eat him.
