i need alot of help
So i have been maining ezreal lately and i usually do well. But last game i got a bad gragas who died to zed mid many times. we lost none of us could kill him. Before then i got a feeding garen who died 2 times because i went top corki on accident. I usually do ok but tit is almost impossible to carry any tips? i fell from silver 3 all the way to bronze. In silver falling was my fault so i got better with cs and not dying as much as well as buying wards. But now that i am in bronze nothing works. and i feel that im dropping in bronze 1 is not my fault. I know the new season starts in a week but im wondering is there any way to win mpre games than lost currently. Im just having some pretty bad problems.
