Don't let duo que hold a match hostage

So I'm just a lowly silver player but there is one thing I have noticed and that when it comes to a surrender vote a duo que should not be allowed to hold a team hostage. The last 2 games I have played consisted of 2 people who were intentionally feeding all game, but it was impossible for us to even surrender because they duo qued and were able to bust the surrender vote every time we brought it up.

So what do I want? One of two things.

1. Duo ques vote should count as 1 person, who ever the leader was who joined que, that is their vote. They can talk it out. What ever, but at least this way they cannot automatically be in control of every surrender vote just because they duoed.

2. Let there be a tier system... First 1 or 2 surrender votes still require 4 votes to pass and surrender the game. Let the second or third time we call for surrender only require 3. This way gives people time to think how they feel about how the game is going, but still allowing for majority to surrender a game by the second or third vote instead of the super majority.
