LS has said something numerous times that completely contradicts Riots decision of adding autofill.
He has said that** everyone reaches different elo differently**.
One person can literally hit diamond with just spamming
jungle as a one trick lee sin main.
That doesnt make him a diamond in general, that makes him a diamond WHEN hes playing 
BECAUSE his success in winning and climbing ONLY came from playing lee fucking sin.
The guy could be gold to plat material with other champs but he got diamond with 
so why should that player like the rest of us be stripped of our chance of playing a champion we would otherwise excel at to be instead forced to autofill where we have no balls on the playing field.
The balls that this player could have on the map with
would never be = to a fucking
.
Because this guy doesn't fucking play 
He plays fucking 
This is one of the many reasons why auto fill needs to be removed from solo ranked queue.
