Tired of being a useless Rango? Well look no further, this guide will help you 1 shot with style.
Just try this build out and sneak into the mid lane and gank stuff, you'll be gaining elo faster than a bullet flying through the enemies ELO. Don't ever go tank Rango, promise me that, completly useless in all ways.

You can max E if the enemy laner has alot of sustain (Mundo volibear lee vlad ETC.)

Pros : You can easly kill everything, Massive dmg and stealth.
Cons : You're squishy early, you're not all over the map befo' 6. Kind of useless in Teamfights if you're not in the jungle.

Rengar's compltetly viable in ranked seeing as he can nuke the enemy carry easly if they're fed, and take a few with you in the grave, RENGAR AIN'T DYING ALONE.

There's no team in Rengar.

Abuse your passive.

So here imma tell you whom to avoid.
1. Malphite
2. Volibear
3. Renekton
If you can manage to play vs any other champion than these 3 you should have an easy lane.
