What about adding a ping for signaling a WARDED area?

Some guys have said it before, but I think a ping that signals that something is warded would be great.

I don't use the chat because there's too much negativity in it, so I communicate by pings. It's really hard to mark that something is warded though, and junglers often waste their time trying to gank a lane because I fail to signal that the path they're taking is warded. I think even just typing "warded" takes time, so the ping would help.

The ping wouldn't have to be along with the 4 others, with the "wheel" you can choose them from. It could be assigned to a different key, because everyone's muscle memory is used to 4 pings on the wheel and not 5.

Also I think a "warded" ping could be useful because it would also time the ward in chat, like "[00:20]: X singals that this place has been warded", then you would know that it will expire in 60 seconds if it's a trinket, or 3 if it's a sightstone ward.

TL;DR: A new ping for marking that a place has been warded. Could be assigned to an unused key. Would be useful for timing wards, if the ping would leave a message behind in chat with a time.
