Why not let Ruby Sightstone give a ward for every kill/assist you get?
Before every team fight, players (mostly supports and Lee Sin players) have to ward their surrounding and end up with no sight stone wards later on.
But with this idea, after you get a kill/assist, you'll get a free ward and able to ward a new area on the map :D
What do you guys think? It seems pretty useful when you can ward the warded area again or another unwarded area for the next team fight.
Plus, if you happened to run out of Ruby Sightstone wards, the next team fight you'll be participating and ACE'd the whole enemy, you'll eventually get the 5 whole wards back for your Ruby Sightstone. #5enemies,5freewards.
