People who surrender or attempt to surrender too much should be banned
The surrender spam is getting out of fucking control, and already people were doing it regardless of context and no matter how fucking far ahead they were.
One game we had fifteen kills, three dragon and eight turrets over the enemy. One sour teamfight that didn't even result in an ace, and the team surrendered.
One game we just hit the twenty minute mark. The score was effectively tied. The team surrendered for no other reason than we hit the twenty minute mark, mob mentality took over, and everyone just hit yes on the surrender without thinking about it.
It has to stop. People who just spam that shit constantly, all the fucking time, should get punished and punished hard. The defeatist mentality is so extreme these days that a single missed minion is grounds to just throw the entire game, and it's getting exponentially worse than that in real time.
