CS EVENLY, WIN LANE BY KILLING THEM.
I'm tired of these lame posts trying to tell you to cs better, yea the first 10 minutes are important if no one is fighting because YOU CAN'T KILL ANYONE, so what do you do instead? Farm it up! Tell me what the point of trying to farm an extra 20 cs is rather than trying to crush your lane? Yea, it's 1 more kill than them but guess what if your lane's even, IT'S EVEN: FIX IT. Here's why you end up with more cs, past the 5-10 minute mark: Fear, they fear you and will not dare to push past where their closest tower is (or was >:D); and if you're consistently pushed it means you want to get ganked and because you're so far ahead because they fear you, they try to help with that gank. Well guess what happens next: you double kill the enemy bot lane because counter ganks and cleaning up is better than diving them under tower, and enemy jungler (think sejuani pre-tankiness and dmg) runs away as if he just baited his bot lane into feeding... because he did. Crush your lane then crush the jungler, then crush them 5v5. Oh hey look i have 100 cs more than my laner and 10 kills up!
If you're not trying to kill your laner, are you even playing to win? Why not try to kill them? I mean think about it, do you know how easy it is to die because they decided to make a play before you did? "Welp now me and my support are dead varus/cait/ez is 4-0 and we're both sitting at 0-2 BUT I'M 40 CS AHEAD!!!" Too bad you fed them your lead >:)
DON'T PLAY PASSIVE, and don't fight them in large minion waves.
vs
ADC match up. One is a lot stronger in lane during the early levels than late game with 6 items, comparatively.
