Fiddlesticks is unplayable in low elo

I love this champ and satisfaction from its ults. But I feel like in low elo I’m just coin flipping when I pick him and rely on my team to place wards and clear enemy wards. Somehow more often than not enemy always wards ult spots whereas 3 people at my team are in single digit vision by the end of the game and I have more vision score than support. How do I play with such teammates?
