Losing is straight up a way better experience now.

When the enemy Trynd is 5/0 and the enemy Syndra is 7/1, they just end the game. There's no more waiting 10-15-20 minutes to end a losing game. The game just ends earlier.
If you're one turret down and the kill score is slightly skewed in the enemy team's favor, comebacks are possible still. But if someone gets stomped it's sooo much easier for the enemy to just end. Hallelujah! It's the perfect balance. Last season there were those games where you'd be 10-15 kills down and 4 turrets behind at 20 minutes and that game would last another 15-20 minutes. Another 15-20 minutes of complete impotence for a 1% chance the enemy makes enough mistake to let you get back in the game. Now it's just 5-10 minutes and it's over.
It's great!
