So I know very little about Hecarim, but I do know that ganking from behind your target is broken op on him. Blown flash or kill every time. If you do it twice in rapid succession to the same person (something a lot of people won't suspect) its a guaranteed kill. I've been destroyed by Hecarims doing this.
Other than that, All I can really comment on is grammar and "professional" language. Using words like cuz and dat and other internet/texting slang devalues your guide. Write with the grammar you would write an essay in. You can use the same "kick the shit outta them" phrases, but make it more readable. Great guide, I've always wanted to learn Heca too.
Thanks , i will correct my slangs...I guess it's how you call them , right?
