End Game Ultra Rapid Fire Feature-----Very Fun Idea :P
What i propose is a Game-Play feature that allows Champions
Versus
to Continue battling on the field of justice (within the base wall) even after the nexus has been defeated.
This Depiction is optimized for the summoners rift map, and of course has some rules and limitations...
1.The Instant the losing teams nexus was destroyed Champions within the base wall would continue to fight To The End until one team(Left Side/Right Side) was left alive in that area.-(Or In Some Cases, Everyone Dies) XP
-
The Winning Team of this final fight DOES NOT Determine which team wins the game; The winners of the game are the players that destroy the nexus.
-
THE VERY SECOND The nexus is destroyed, EVERY SINGLE Player that is within the base walls will assume the powers that you have in ULTRA RAPID FIRE Gamemode!!!!
-
All of the cooldown and mana etc...Effects that were present in URF Mode would be active starting the instant that the Defeated Nexus ran out of Health.
-
If one or more players from either team are not within within the border of the base wall (Last Fight) area for a Period Of 10 Seconds, then the game would end; the team that defeated the nexus would be named winners, even if the winning team of the (last fight) is the team that failed to defend their nexus.
-
The last fight can go on as long as it needs to until one team is left standing, or one single team is isolated inside the base for 10 seconds.
-
There will be a for-fit feature so that if one team surrenders,AFTER THE NEXUS HAS BEEN DESTROYED, it will only end the last fight, and not determine which team wins the game; the reason for this is because there will be instances where troll poll fizz
can escape from the last standing Leona
on the enemy team, and delay the ending of the game indefinitely. There will be no shame in ending the game if they can not kill you but you can not catch them within the end game area.
Please make a vote on the pole system, questions and comments please 
I believe this could be a really cool standard feature, i like how fun and interesting it sounds, i hope everybody else feels the same way :P
