Time to location
Example a jungle is about to come and gank an enemy and they say they are on their way it would be able to tell them how long the jungle would be until he gets there so player can bait or tower hug until he arrives. Another example would be if a teammate from other lane needed to help another lane that's loosing can ping how long it will take for help to arrive or to take over a lane until they can return.
Don't judge on spelling or grammar I know this is the internet. Let me know if you guys think this is a good idea
