Make that 5. Name one single person who sees an autofilled peron and says to themselves, NON-SARCASTICALLY "Nice! We got an autofill! I like our odds this game" No one. NO ONE SAYS THAT. Many people who are not the autofilled player get tilted the second they hear "wtf" immediately upon entering lobby.
"Just role swap with them"
If I wanted to role swap with every autofilled player, guess what. I'd queue as "fill." And if I did roleswap with every autofilled player, I may as well put fill anyway, because of how absurdly common autofill is. It's actually hilarious.
Just the other day I was trying to get into a game, I get my primary. Cool. Then a dodge
I get my secondary. Eh still fine. Dodge.
Then I get autofilled jungle. Oh hell no I don't wanna play Rammus or Amumu today. Dodge. Phew
I get autofilled adc. RED ALERT. RED ALERT. LITERALLY WORST ROLE. Dodge. Thank christ.
I get autofilled support. Eh this is fine, I'm not a ba-Dodge. Okay then. I literally got every role in the game and had to play none of them.
I exit the queue. Come back 5 minutes later. I get my main role again. Proving to me if Riot just held on for just a few minutes, no autofills, probably next to no dodges (No way in hell no one dodged due to autofill out of 5 lobbies in a row), and we'd all be in a game MUCH faster. Autofill is beyond unnecessary, it's harmful to wait times.
EDIT: Just realized most of this was salt-fueled rambling, sorry. I didn't intend for this to stray so far from the original comment.
