Since Summoners aren't (and haven't been for a while) canon anymore, why do we still have the Rift?
What's the point in fighting on this map? Why do the champions take precious time out of their day to go fight on this massive, tower filled battleground with weaklings for soldiers at their side? Is there a motivation behind this? What good is destroying a nexus at the end of the day, what do the champions gain from it; what do they accomplish?
All of these, I think, are great questions, and unless I'm uninformed I don't believe there's an official explanation for this. I wanna know why Aurelion Sol, the creator of the universe(s), decides to miniaturize himself from a massive star-dragon just so he can beat up a bipolar rat with PTSD.
