Vision Control

Vision is such a critical part of League of Legends was wondering if a effect of warding could be placed or does this seem just a worthless thought or such. Green wards have 3 HP or hits before it is destroyed or becomes untargetable. Wondering if AA'ing the ward could or should remove 33% of it's life such as;

Warding Totem (Lasts 1 minute) Where hitting each HP off it would remove 33/67/100 seconds off its placement time. Like early game say when a ward is placed and is immediately hit each could remove said amount of time of it, which could be seen as fair forcing Summoners placement and awareness to increase. Also the same with Stealth Wards that last 3 Minutes where each HP would remove 1/2/3 minutes off placement time, wondering if this idea seems nice, correct, or just too tedious.
