Delayed Input: My favorite thing about Nexus Blitz is...

That Sudden Death happens at a fixed time. The event itself isn't what gets me though, it's that it pretty much guarantees that almost no match will go for longer than 20, 21 minutes tops. If I was semi-limited on time and I wanted to ensure I didn't get trapped in a 40+minute ARAM or an hour long SR game, I could pop on Nexus Blitz and feel comfortable playing, knowing that there's basically a fixed time the game will end around, so I don't feel like I have to rush and make stupidly risky plays to try and snowball and end faster, or feel uncomfortable queueing up at all due to time constraints! I could just play it normally, even on a timecrunch.
