Lee Sin could see my wards

I just had a game where i put 3 wards in like a one minute period and lee sin put them all down without a trinket. I heard something about his tempest being able to do so. Couple that with a rough experience with a rude ADC, It made me fume. I was fuming every time lee sin was doing that. The player was aware how too and was using that "glitch/bug" i am assuming, Please fix riot
