Stop blindly following builds you see on stream!
I currently see a blue build ezreal every other game, and they get confused when they aren't dealing as much damage and a Draven with infinity edge. Blue ezreal is good for kiting and launching Qs safely in team fights, not Eing in and trying to do the buckwheat grotes. While it does provide good self peel, no one in lower elo where I play know how to abuse it and usually ends with ezreal feeding.
