I've played countless games testing both, and I'm still not 100% sure if RFC is the right choice. Personally, I still really like Rapid Fire Cannon, but I won't deny that Shiv is definitely a great choice. If you manage to crit with your first auto, you will do more damage if you have IE. IE is expensive, and I usually don't get it until a little later in the game. I like get the Shiv/RFC before IE, and RFC just does more damage early on. I think the damage is only different by a margin if you crit in the late game. I love the 2% movement speed and I usually find myself running across the map in stealth. I wouldn't shun anyone for taking shiv, I even put it as an option. I'll be sure to place a note that it does more damage with the Crit of IE. I appreciate the feedback! Thanks :)

I just had a thought, wouldn't Shiv be a better option than Firecannon on Rengar because once you have the bonus crit dmg from Infinity Edge it will do more dmg. And it helps clear JG camps as well. This would make your burst a bit more potent. Great guide btw! :)

While that is true, I find that empowered W on this build helps sustain much better throughout the jungle imo. I'll make sure to put this in the build for others to know! Thanks for the feedback. :)

Many people have done the math on it, and have shown that using empowered Q is better for clearing than empowered W
