i love it this build is hilarious trolling it works and it makes sense what more could you ask for

Thanks a lot! I thought I made mistakes... but so much!? T.T
Was freakin' me out, i really tried to look for every single "u" and made an "you" out of them and yet one survived x´D
And yeah i wrote the guide cause there was no AP Rengar built on Mobafire yet!
Thanks a lot again!;D

I know English is not your native language but you should try your best(I'm not saying that you aren't) to make it easier and more understandable to those who do read English. So there are a several things.

• Rengar is a melee champ and his Battle Roar doesn't have too large of a range. That means that he will be very close to enemies. I think that you should also provide a second build with more sustain(ex: armor and magic resist).
• In the intro: "First of all, it´s my first Build and english is not my native language so if you find errors please PM me to get my Guide rid of those!"
  • It doesn't seem like you are using normal apostrophes which are just ' not ´. You don't have to change it if you don't want to. It's just a little thing I noticed.
  • Rephrase your sentence to: "First of all, this is my first build and English is not my native language. If you find any errors please PM me so that I can get rid of those from my guide!"
    
    You don't have to capitalize build because it is a general term not a proper noun or name. English like all other types of languages should be capitalized. The sentence is a big run-on and people need time to take a break and get some air. Split the sentence into two parts. The last part of the sentence is awkwardly worded so I rephrased it for you.
• "Before we start u should watch the Summoner Showcase- Phreak explains him AD but you see how his skills works, aswell as his skillrange and his AA-Animation(<--handling)!"
  Change it to:
  "Before we start you should watch the Champion Spotlight. Phreak explains Rengar as an AD champion but you will see how his skills work, as well as his skill range and his AA- animations(<-- handling)."
  • Try not to use shortened terms like "u". We want the guide too look nice and stuff not something that looks easily typed.
  • It is a "Champion Spotlight" not a "Summoner Showcase".
  • Using "him" is too vague. Replace it Rengar or else people might think that Phreak is talking about himself when he says "him".
  • "As well" is a two word phrase not one word, "aswell".
• " Well i found out that Rengars Battle Roar has a 1.0 AP ratio!
  You could answer this with, "Dude! Veigars Dark Matter aswell has a 1.0 ratio. Not to mention Primordial Burst!" Sure. But thanks too Rengars passive ( Unseen Predator) he can "almost" double Cast Battle Roar."-->
  "Well I found out that Rengar's Battle Roar has a 1.0 AP ratio! You could answer this with, "Dude! Veigar's dark amtter has a 1.0 AP ratio as well. Not to mention Primordial Burst"! Sure, but thanks too Rengar's passive, Unseen Predator, he can double cast Battle Roar when he has 5 Ferocity."
  • You forgot to capitalize I.
  • Add in ' because it is Rengar's.
  • Again it's "as well" not "aswell".
  • Why mention Primordial Burst? It has a way better scaling and base damage than Rengar's Battle Roar, is single target, and Veigar's ulti. I don't really see a reason to compare to so very unlike things.
  • Sure isn't a complete sentence and should not be left by itself. "but.... Battle Roar" is also just a dependent clause so you add it to "Sure".
  • Don't say "almost" when Rengar can, without a doubt, double cast Battle Roar(if he has 5 Ferocity).
• ""Huh!? Thats all!? Its not even (really) ranged!" Well Rengar has a pretty good gapclosr in my opinion. his passive is good when your top, and later your Thrill of the Hunt has a 50 second CD(without CDR).
  
  It´s really a AP Glasscannon-Burst Guide yet but i try out more, and keep you updated!
  But let´s analyse this step by step!"-->
  
  "Huh?! That's all?! It's not even "really" range!" Well Rengar has a pretty good gap closer in my opinion. His passive is good when you are top, and later Rengar's Thrill of the Hunt has a 50 second cooldown( without applying CDR).
  
  It's really a AP Glass Cannon-Burst guide but I will try out more builds and keep you updated! But for now let's analyze this build step by step!"
  • You don't need to have "really" in parentheses. When trying to add a sarcastic or questionalbe tone just put the words in "quotes".
  • Gap closer is a two letter phrase not one word.
  • It's "you're top" not "your top".
  • Just like build, "guide" is a general term and does not need to be capitalized.
  • Glass cannon is a two word phrase not one word.
  • The phrase "but yet" contradicts itself. You only need either the "but" or "yet" not both.
  • Spelled "analyze" not "analysis".

As you can tell these things are mostly just from the Introduction. Your guide has plenty of spelling and grammar mistakes but it's hard to spot them when you are not fluent in English. I will try my best to proofread your guide but I still have my own Rengar guide to worry about. There have been many AP Rengar guides ever since Mobafire was flooded with AD Rengar guides. People got bored of them so they wanted something new and AP Rengar was the thing that they have been looking for. Good job on your guide +1 :)

Edit: Oh yea. You should also "Require a comment to vote" so that your guide will not get troll voted as much.
