[2019] Nobody is talking about the Thresh vs Senna event ?

Sorry if this has been done before, but i didn't see a thread about it.

Like with some other event like Kha zix vs Rengar, if a Thresh and a Senna are on opposing team, they can unlock a quest. I've only seen it from Senna's side where it's called "Sentinels of light don't fear the dark"

At the moment of the quest, Senna just reached 100 souls, while Thresh had 40. The win condition for Senna was for her or Lucian to damage Thresh 3 second before he die, to gain a fragment of his power. This game, Senna won the quest and stole all of Thresh's soul.

Sometime, it's fun to have some weird quest condition that give a big buff because the quest almost never happen, but .. this is way too big. In this game, since Thresh had 40 souls, he lost 30 AP and 30 armor while Senna gained 30 AP and 30 armor. Maybe gaining the stat is good, but stealing them seems .. too much. His passive make it so he doesn't gain armor by level, and Senna can just .. stop that from happening late game ?

So, for other people who saw the quest, and saw the other outcome (what happen if Thresh kill Senna, he gain AD, Range, Crit and lifesteal ?) what do you think of it ?
