Ezreal Bug

Hello, just wanting to report a BUG! Ezreal, I have noticed Ezreal was only doing 72 damage on turrets. This was late game and I almost finished my full AD build. I had about 345 damage and I was doing that amount on inhibitors, minions, champions, everything except turrets. I honestly think Jana was doing most of the tower damage. Needs to be fixed, I have noticed this about 3 times. 3 times as in 3 games. So yea love your game RIOT but please fix my main.
