just some of my opinions, it could be wrong.
i saw alot of tryn starting with a phantom... i dont think its working much as it has no dmg and many of them are looking for two phantom..i think thats really low dmg output,
i start with a hp regen 20hp/5s rune, then i farm a infinity edge in 20-22mins in most common cases, if good luck(facing a nooby player), i can have it in 16-18 mins, then it should already be able to killed every opponents on the battlefield...after that, sell the rune for a life steal 12%, then straight go for last whisper, now you shud be able to crit them for 300-350 dmg...(in around 28-30min)
and then, they are f-cked
people always level up bloodlust but actually spinning can do alot of farmings for you
the weakest 4 creeps on the corners of the mid lane, u can kill them in one hit with spinning until the mid game, if you are teamed up Fate, its something really cool to have the 2 bonus gold
just my point of view, im not trying to say that im pro or something, feel free to leave your comments
