idea for increasing the awareness in game play

Hello i have been sitting on an idea that could potentially increase the affect that wards can have on game play on summoners rift. For lack of knowing a better place to suggest i suppose i shall just post it here. Please give me feedback on your opinions and any other ideas related to this. I use wards fairly often in games while i support in the bot lane and in the heat of battle you tend to sort of loose focus on if sombody has wandered into the range of your ward. (resulting in horrible chaos aka the gank)** I would like to suggest that there be an upgrade option in the shop that will allow the users wards to make a warning ping when sombody enters the wards field of vision.** i feel like a noise and maybe a danger ping would greatly increase the effectiveness of wards in games. it would also increase the amount of map awareness for early game players and help them learn to pay attention to it more.

Thanks for all that you do Riot keep up the work! ;)
