Players should have the option to ping "Need Vision"

So my thought is... we have the "Enemy Has Vision here" ping, however when you're in solo queue and you find yourself in a situation where you no longer have wards to place you should have a "Need Vision" ping so you could point out objectives that need warding or good ward spots to your teammates. it would solve Riot's problem of lower ranks not warding enough if you could help your fellow players remember by pinging. if you do manage to get around to putting it in (because i know riot has alot on their plates atm with the new patches) you could make it the same as the "Enemy has vision here" ping but then just make it blue and have a different sound.

Thanks for reading
