Early Surrender
Since I can't login to comment on patch notes, I'll do it here. Unanimous surrender at 15 will almost never happen, even if eveyrone knows it's lost someone will have never surrender attitude or just troll to waste everyone's time. I suggest you make it 4 votes for surrender and add a condition if the enemy has 10 more kills and 2 more turrets, or just 15 kills, something like that. Another thought is that higher the rank less likely the surrender for stupid reasons, say bronze and silver players may want to surrender after 1 death or after just a 5 death lead(happens in plat too but much much less). Also the turnover rate is higher as in lower ranks even the 15 deaths lead can be lost with overstaying or reckless diving. So what I'm saying is, higher ranked players know when the game is lost hard even in the 10th min and are less negative hence they know there is at least a ~20% chance for winning, any less than that is better to surrender. Here's another one, if a player voted nay/yes 20 times in a row(including each game's multiple votes) he can't vote for the next 5 games. Uh hope someone is reading this, those are really good suggestions.
