So I've met all the requirements 20 kills+assists...got even over that...I was Lissandra in my team against Ashe in enemy team...it was Summoner Rift normal mode...we both had level 18,the min was 43 and the quest didn't appeared...last time I've got this quest was in 2014 or so.
So this is a bug or they disabled this quest?

But onto your post and what the other guy said. He was asking if 
was in your game for the reason that if she was then the quest can't trigger if all three are in the same game. The other thing you need to know is that both players have to get 20+ added kills and assists. Ashe only had 16 so the quest didn't meet the need requirements.
