Obviously you can't see who voted. I said usually because I was referring to the way the system is abused when the game has gone to a blame game shit show. I wasn't referring to a legit surrender. I can honestly say that a large percentage of FFs that I am involved in are complemented with trash talking and toxicity, and when it gets to the point where it's like.."just surrender." You get the 1-2 people who press no to troll.
example that has played out thousands of times IRL: Jungle didn't go bot, but was able to help get top or mid rolling. The bot lane gave up first blood and continued to feed...right around time the enemy botlane shows up 4 kills deep to midlane you get the classic "jg never came bot. gg. horrible jg." Now, at this point usually..note I said usually.. the team is split into two varying opinions. The crusty adc who has entitlement issues and blames the entire game on the jg, and the jg who fights his case that he was in fact actually helping the team. When the argument breaks out you know, regardless of what you say YOU KNOW, it's all down hill from there.
It is an option that won't be detrimental to the game, but could alleviate some of these issues.
