Surrendering in Ranked Should Be Removed
I mean surrendering in normals and game modes aren't a biggie because no one cares about them and usually are played for fun. But ranked is supposed to be about never giving up no matter how fed the enemy team is to secure the win and try to execute a comeback. Ranked is the competitive, taken seriously queue in LoL. Death timers in this season are ridiculously long, so even if the enemy team is in the lead killing them will most likely result in a game winning team fight.
The TL;DR is I'd rather have a super slim chance at winning than 100% losing a ranked game.
