I really enjoy quests such as Khazix vs Rengar in-game. I would like to see more if possible? after reading pyke bio; I don't know why but many of us expected a quest between Gangplank and Pyke.
It doesn't have to have a huge impact on the game just a buff of some sort
Garen vs Darius ect
I thought that Kat was Garen's secret girlfriend...(taboo love interest, whatever)
Darius is identified as Garen's rival, since Garen had two Darius-specific taunts.
braum vs nunu, if you read braum bio it would actually make sense
So how do we make sure rito gets this great suggestion?
Please, don't let this topic die!
You forget the most obvious , 
VS 
Their lore even the animation for Lucian when he relesased, EVEN THE VIDEO "climb" had them vs eachother
why no vs thing for them
Garen vs Darius ect
garens rival is katarina and not darius.
i dont even understand why darius was chosen for the event. especially considering that just like garen, katarina doesnt have a legendary yet as a season 1 champion, and darius already had one (and a gemstone skin).
There are surprisingly many champions with rivalries that can work for this
vs 
vs 
vs 
vs 
Just to name a few
if 
/
and 
are on opposite teams then there is a perk where if one kills the other the killer gets extra gold. likewise if and are on the same team they get bonus gold when they help each other on a kill.
