Renekton is an early game tank/laner/scrimisher with a rage bar.
I suck at renekton
If you ever get into multiple fights early game he is the ideal hero to have other then riven.
With 0 mana costs it makes him a very effective laner with his skillset, and a really strong bait game.
Since renekton has an short jump that can jump twice, he can afford to go heal ignite, instead of ignite flash. This gimps your flash W initation but it gives him so much more map presence. throughout the game.
The bad thing about renekton is his late game sucks, but his strong points are a strong early/mid game and is very effective with alot of resistant items to counter your lane because of his ult that gives him HP. He also benefits from cooldown items.
If you have problems with controlling mana, want to rape from the start, like interior crocodile aligators then renekton is the hero for you.
Since you're a crocodile you never lose when you're in the river. HUEHUEHUE
As always the interior crocodile aligator song is appropriate to listen to while playing this hero
