I hate the "never surrender philosophy"

C'mon bro, the game is already 0-15 in 8m game, ALL the Champions in the enemy team scale better, why would you not Just surrender?

Even in 4fun modes, when you are not having Fun, all your team are getting stomp, you can't play because the other team are made of Full cancer Champions, people still not surrender, it's A ROTATIVE MODE WHY WOULD YOU NOT JUST MOVE ON?????? You are not gonna lose Anything, like WTF
