An idea on new pings

What if we have pings for specific champs for specific tasks?

For example: pings champion 1 to defend tower A. Or champion 1 and 2 to defend tower A.

This way, when you ping for assistance to protect a tower, not everyone on the ENTIRE team swarms in protect a tower. Or when you ping to gank a split pusher, not EVERYONE on the entire team swarms to get him, and then the other team take out a tower on the other side of the map. This way you can direct your team better.

You can be like, champ 1 and champ 2, defend tower A. Champ 3, 4, and 5, gank enemy champ 1. Also, now that we have the "enemy have vision here" ping, I think we should also add a "does enemy have vision here?" ping, and a "please ward here" ping.
