Dragon Auras

It seems that most League of Legends players are more focused on kills rather than objectives. I had an idea on how to get players to want to go after more dragons. The solution is Dragon Auras. Every 2 dragons your team has (2,4,6,etc.) will give your team a different colored aura upon killing Elder Dragon. I'm open for color suggestions, might as well have the colors players want. I think this would be a cool way to get players more focused on dragons that wouldn't effect the game in any way. Thoughts are appreciated! :)
