But of course, we need to make sure we can swap champions in champion select right! This totally isn't complete and utter bullshit, and it totally needs to stay in the game forever! It's not like Riot has one of the most successful games of this era and has a staff that is paid to fix this type of shit, but nah, let's continue allowing people to experiment with champions in ranked queue.
Honestly, though, I can say a good 20% of my losses are due to people playing champions they're unfamiliar with. That's 1 every 5 games, sometimes 2 if the day is really out of whack.
