Battle for Freljord (and other secondary quests and hidden passives)

So, we all know and encountered secondary quests and hidden passives, the most popular being between the leaders of the Freljord, Jinx, Caitlyn, and Vi, and Rengar and Kha'Zix. I personally love the Battle for Freljord one, and every time I encounter it I focus the enemy Ashe and nothing else to get that crown. The quests and passives are great, but I wish something a little extra would be added to them once you get out of game. For example, if Rengar kills Kha'Zix first he gets the "Head of Kha'Zix" summoner icon (creepy passive face). Or, whichever queen kills the other first they get their tribe summoner icon along with an ice crown in the middle of it. Or maybe a banner. Something to spruce up the game and make quests more fun for everyone. It'd be in PvP of course, between two humans ( don't feed and then kill Ashe bot mercilessly).

TL;DR - In addition to the in game buffs that come along with secondary quests and hidden passives, if you happen to compete the quest successfully you get something to show off out of game like a summoner icon or banner. PvP only.
