Two ping ideas i think would be VERY important to have

First off. to be able to ping how close you are until your next lvl (aka 92% of the way until lvl 11) what REALLY help me team realize why i want exp before we teamfight

and also.. to be able to PING an item in the show to say "56 gold away from "

or ping the item to say "enough gold for "

another thing that isn't ping related but i think would be very useful is a little popup for the support at say around the 10 min mark that says: "you have not purchased a yet, it is recommended you do this as soon as possible"
