I see an inherent problem with the VS lore.
This event is cool and all, but the potential ending has me a bit confused because, well.......
Neither side can win.
Come on, we've all seen it. From Diablo to Marvel, the whole "Order vs Chaos/Light vs Darkness" thing always comes down to there needing to be a balance at all times, and if this balance leans to heavily in one direction or the other, all hell breaks loose (even if the "good" side wins, and even worse if the "bad" side wins).
So, why are we competing with each other, if the inherent outcome will be overall negative?
I don't know. Riot's planning something, obviously, so, we'll just have to wait and see. It was just a thought I had.
