Duration of Wards increased

YO, i have a problem with the wards since Patch 5.1. Normally if you place a ward it is almost impossible to kill it in bot, you really need fast aa with your adc or you are . So right now you almost can kill the ward solo, the duration of visibility did increased! Its much easier to destroy the ward, I did it solo on Nami today and when my adc aa it 1 time it's guarantee destroyed 75 gold are gone and you dont have vision just cause of the increased duration. This needs to be fixed!
