Lol.... Well if you are in bronze, syndra may not be the best to play, she has a very high skill cap being mostly skill shots, same with zed, though you can still do a lot of damage without trying. I would reccomend Udyr(dont spam too much early or you will have no mana), skarner can be good, shyvanna, chogath. Those are a few easier junglers.
Top champs like riven and renekton, while having a high skill cap, also have a low floor and can wreck faces without much effort. Voli, mundo, shyv, and nasus are rather straight forward, though nas needs a lot of cs. Teemo is one of my favorites, but im not sure how he is in bronze.
It's not like bronze players can't land skillshots at all lol.
No, but they will have far better luck with champs that dont have many of them as they will have far more reliable damage.When picking up the game or being unskilled, play something simple to get better. Everybody has to start somewhere. I actually played karthus every single game but 2 from lvl 1-30 back when the game was first released, then when i got there i tried annie and realized why i was having such a hard time.
