Turret bug, in aram and summoners rift

I noticed this bug in aram first and still hasnt been changed. the turret damage is all over the place. attacking someoen in aram under turret, first shot did around 25% of my champions health and other times it will do nearly non. many have died/lived multiple times on aram because of this bug doing alot of little health. its nearly impossible to predict the damage those turrets will do. and this bug i might have found surprised me a bit, the turret damage bug is like the one on aram but i only seen this 1 time, and im a support main and i found this bug on a turret dive. I play tanks alot and tower dive alot so i am always counting the turret shots. Now i could have counted this one wrong or something but i was near full health on a tank we turret dove and the turret hit me like 2 or 3 times or so and i died. i was past lv 6 so my health from items and armor was up i just dont really know what happened i took maybe 1 or 2 shots from the enemy adc but he wouldnt have done much. I just wanted to bring this up because of the aram turret bug and see if anyone had a similar issue on summoners rift.
