Why you should never surrender in ranked ((Unless a Remake thing pops up, then always remake))
As the title suggests, I'm a firm believer that you shouldn't surrender in ranked, unless you've got that remake window, Why? Well, lets take my most recent ranked game shall we?
So we are losing heavily, but our team is not surrendering. Enemy is knocking on our Nexus, and it looks like GG when thanks to the work of our Sivir, Leona, Ekko, Rengar (Me), and Kennen, we successfully repelled the enemy from our Nexus. Now, this is where we have a chance to come back and win when kennen DC's. Well, we lose. Horribly, thanks to him DCing.
Simply put, Ranked matters. Even to some of us Bronzies, who want to improve, get better, and leave the hell known as Bronze. Surrendering turns whatever slim chance you had at turning it around into a big fat 0% chance of victory. You don't just have late game, the longer the game goes on, the more likely it is that the enemy team will make a mistake, which is why the other team wants you to FF, they are worried about themselves making an error which costs them the game.
Now, I'm sure you're thinking, but what if it looks really hopeless and stuff, like a 16/0/0 Rengar problem. Well, yeah you're probably shit out of luck, but it's ranked. You're better off trying your hardest to come back and win then guaranteeing the lost LP. Is it more than likely going to end with your team losing horribly? Yes, but at least you fought until the end, and gave it your best shot.
And for the love of Aurelian Sol, don't DC in a freaking ranked game, especially if your team just successfully defended against what should've been a GG WP nexus push.
