If you think going on your smurf and picking something you never played in ranked doesn't matter..
..then you're a complete dipshit.
I don't care if you pick TF ADC. If you are actually trying to win the game with TF ADC (please don't do this), then I am 100% okay with it.
But if you're gonna play something that you have no experience on, that's a red flag. Because although this isn't your elo or main, it still matters for the other four people that are playing alongside with you because THEY'RE on their mains trying to rank up, just like YOU on your main, right?
This also applies to people who int on their smurfs because it doesn't matter on that account. While they are right, it's 110% not right to ruin others ranked play. Just think about it, someone inting on YOUR main?
