Vote For Tie

What are your thoughts on having an option for both teams voting for a tie in games that drag on too long? Maybe something like 7/10 players saying yes would be sufficient in the game ending in a tie. It's frustrating to have games that are 40+ minutes, everyone has had a full build for 10 minutes, and nobody wants to surrender. Not sure how other people feel about extraordinarily long games but in my experience once it hits the 50 minute mark I don't even care who wins at that point. This would only apply to normal games.
