So you're probably thinking 'Iron how do i actually kill people in lane with this build' and the answer is very simple. You dont, thats not the point of this build. The point of this build is not to carry the game, its to carry your team and allow them to play better than they otherwise would. You'll be dealing with people who suck at league and flame you because you arent running the 'right build' or 'right runes'.

Your job in lane is to hit the enemy laner and try to farm DH stacks so that late game you can kill anyone who comes to you 1v1. Farm well or decently well and you'll never be so far behind that you cant lane. If you're struggling with farming go into practice tool and cs as Vlad with no items for 5 mins before jumping into a ranked game. It'll help you warm up those cold hands and should give you a better chance at actually last hitting.
If you follow this advice you should be able to win 75% of games.
Like i said though, this build IS NOT for carrying games. You'll almost never be 9 kills 0 deaths 5 levels up because you're not playing for kills. You're playing for objectives.
