Instead of crying for nerfs, recognize weaknesses and learn to counter instead.

Locked in your mid laner as a first pick blind and the enemy thought to himself, "Hmm, they first picked a super squishy mid laner with no hard CC and no mobility for dodging my Zed mekkanicz"? Never fear! The based Rito Gods have provided you with two items
to deal with arguably the easiest to counter assassin in the game! Uuuuuuuuuunbuhleevuble!
Don't want to build these items because they change your standard build path or you don't like buying them anyway? Then don't complain when you get assassinated.
I only use Zed here because of the most recent thread asking for a Zed nerf. It brought up great discussion, and I enjoyed everything from both sides. But ultimately, Riot has done a good job of giving Zed and others clear counterplay. Sure, they may be frustrating to lane against (and honestly, even this isn't true if you counter pick well; rarely when I pick Annie into Zed do I have a hard time managing mana or farming well, for example), but in some cases such as Zed, a strong landing phase is his biggest strength, because a Zed that falls behind generally stays behind. He's a great early and mid game champion and a weaker late game champion.
I'm on a phone so formatting and content are probably lacking, and I'll edit later.
But anyway. Before demanding nerfs, I ask you simply consider counterplaying the enemy. In fact, play that champ you struggle against. Then you can better understand exactly what their strengths and weaknesses are first hand :)
The goal here is ultimately to help people realize that counter-picking and counter-building are two vitally important aspects of League. Counter-picking may not have as much impact in lower elos, but it is still an important concept.

? Never. Regardless of who plays against them or what is built against them, these champs never have to build anything in lane in order to counter their opponents
