Maybe it's the build, I don't know. I build Ezreal different almost everytime, but if you wanna know how I carry all the time... In the beginning, boots and pots of course. Position yourself well, and poke with Q. Normally, I don't even get W. It does no damage, but slows attack speed. go back, always build phage first, with a basic attack, or a Q it could slow them. From there, build trinity. After trinity, I make the decision of buying a Phantom dancer, or a BT. If I go phantom dancer first, IE comes right after. If I go BT, phantom dancer comes right after. After that, what I get next depends on what the other team buys. If they have armor, I get a LW. If they don't have any armor, I but IE if I didn't get it, or if I bought my BT and PD, I buy more life steal. I normally don't know what to buy after that, because I rarely ever get there, the other team ends up surrendering. But by the time you buy your PD and IE, you should just auto attack.
