At a certain gold discrepency surrender should vote in favor of 3/5
There are just some points in the game where you wont win. For instance your entire team has taken 0 towers and the enemy team has all of yours in lane and a couple in base. I dont think it's fair that we should be forced to drag on because 2 morons though it would be a great idea "to keep fighting valiantly till the very end" like some romanticized hero. This is reality and we have lives. if we can end one game and go onto another one, then by all means let us do so if the gold difference is extreme enough. 3/5 is a majority vote. I think it's fine that to surrender you need 4/1 but at certain points in the game 3/2 should also pass
On a second, somewhat unrelated note, Would you agree that the Gold totals should be available in game to be seen. Ive seen arguments against this on other boards such as this http://forums.na.leagueoflegends.com/board/showthread.php?t=3318906&page=1
but honestly it cant be anymore of a throwing magnet than seeing the team scores being 2/20. I think Gold should be an available stat with it's own screen that shows if you're falling behind or catching back up (falling behind numbers in red, green for catching back up), and to see gold total by champion, so you can see who has the least gold and build around it. while it could lead to toxicity toward the weak link it's no worse than looking at a 2/7/3 champion and flaming him.
I also think some other stats should be visible for instance, number of towers taken. by a person or objectives secured.
