It was downvoted because it was terrible when it was released.

I dont get why so many down votes are on here, troll voters mad yours is better than theirs. This is great man, thanks for the help, it made my games as him way better.

This build is great-looking and I dont see why its downvoted, u spent time on it and the build is good, dont listen to the others

Too many things wrong with this, its too early to elaborate but here's your -1.

P.S: Trollvoting other Rengar guides to get yours higher is extremely low ****, ik it was back in like January but still, not cool.

Scaling MR isn't as good as flat MR if you're going to be 1v1'ing a mage for the first 9 levels.

E W Q R is worse than E Q W R because E places you right behind your enemy, and the smallest of movements to the side by your enemy can dodge one or both of your W hits. with E Q W R your enemy has time to try to walk away from you, and while they're walking away you throw W in that direction as they can't dodge it at that point, because of W's wide range the further it goes.

You shouldn't have a Trinity Force in your item build at all. In my old guide I explained why it was bad, and that was in season 2. Since then they've made items even better than Bloodthirster. Trinity Force is the last item you'd want to consider on Talon now.

There's no reason this guide should have that many negative votes. Guide is easy to read/follow, has great coding, and probably took alot of time to make. People don't just put that amount of time into making a guide for a game they'd know nothing about. You have my upvote, man. Thanks for posting this.

Revisiting:
Still no Veteran's Scars.
Runes are fine now.
Ability Sequence looks fine.
You added to your matchups section, which is good. However, you didn't fix Diana's difficulty.

I appreciate the work you continue to put into this guide, but for now my vote remains the same. I'll keep checking back, but keep at it.

Wayyyyy too squishy build.

Nothing to add.

You build Black Cleaver way too early, you have absolutely no armor at all leaving you extremely susceptible to auto-attack harass at the start of the game by ranged champions, you take scaling MR vs AP casters, you recommend Iceborn Gauntlet, you seem to prioritize Trinity Force over BT when Trinity Force should barely ever be taken in the first place, you recommend E > W > Q > R over E > Q > W > R or E > Q > R > W.

Just has way too many flaws.

Lol'd.

(Lagger is joking)
Scaling AD Seals on a snowballer? plz no.
Saying that your ******* Early Game includes a BC and LW is messed up.
Iceborn Gauntlet on Talon? Say it ain't so.
Masteries are alright.
Good BB Coding.
Matchups are blatantly wrong at points (Diana should stomp Talon. Kat should lose to Talon. Kass should get stomped by Talon. Vegiar should be an easy lane.) You don't include other AD Mids, who tend to be strong against Talon.
