if you just started, and your above level 20, get runes... may not be as glamorous, but it helps 5x as much than getting a new champ. and also, difficulty level shouldn't "scare you", but if you just started, stick to easy champions. its the best way to improve and i doubt your mechanics are good enough on someone like zed. And even if they are, you should be focused on the game itself rather than trying to get down the mechanics of a champion, so easy champions are the best for starting because it allows to focus on the mechanics of the game rather than just the champion. If you REALLY want a champion to play. Get Fizz, he isn't an ad assassin but he is broken, easy to play, and is 4800 instead of 6300. Really wouldn't recommend getting zed tho, even if you can play him properly, you definitely cant play him properly and focus on the game mechanics at the same time. P.S. ignore the "stats" on the champion page, they are complete nonsense.
