Why does surrendering require someone to abandon?

So you go through several rounds and the score looks like this for your team:

2/0/6

1/0/6

0/1/6

0/0/6

0/0/6

vs the enemy (who's better than you, or your team sucks or they're hacking).

9/2/1

7/1/0

5/3/0

5/0/1

4/1/1



Why does it require someone leaving just to end the game? It's pretty clear the losing team doesn't have a shot (okay there are miracles that happen, but realistically this is going to end with a 16/0 score so why if there's 5 people who wish to resign can't do so?

Or take scenario #2 you've got a griefer you kicked. And it's 5v4 against an already better team (granted you can take over a bot provided it isn't picked before that) and it's the same hopeless situation. Why does a player who has been kicked not suffice as enough reason to vote to surrender?



I believe that surrendering should:

1.) Be an option if you're losing by a 5 round split.

2.) You kicked someone on the basis of being an idiot and don't want to fight a losing battle (I'm aware that this might be abused, but believe it's preferable to being stuck in some game vs a hacker who's just going to farm kills). (Again the vote must be unanimous, if there's even one who wishes to try to comeback, that's their decision).



TL;DR Allow surrenders if the losing team is 5+ rounds behind or if a player is kicked.



Any thoughts?
