I am a silver 2 player.
Why am I matched against a diamond Lee Sin?
Why am I matched against a diamond Lee Sin?
Because they wanted to teach you a Lee Sin.
get it? anyone?
ok i'll be going now.
BOOOOOOOoOoo I cannot see why you did that 
Ah, that's a good distinction: Diamond Last Season. I've had Golds and Silvers in most of my Bronze games. Many people dropped hard. For a Diamond to fall so far I'd imagine he tanked his prov's hard.
So, Riot logic, a diamond who blows placements is literally the same as a gold player who wins most of them?
Guessing this was in a Team Builder or ARAM? Guessing he was duo'ing with someone much lower ranked.
Ranked solo queue.
You can't kill Baron in ARAM, and if you look at the game mode, it says Ranked (Solo Queue)
Link the game from your Match History.

Diamond last season.
We all had silver/gold borders.
I thought someone of a higher ELO and division couldn't duo with someone who was 2 Division's lower. In this case Diamond duo with Silver.
Riot implemented new system to actually check if Lee sin isn't too weak. If he loses, he will get buffed.
It happens at the start of every season. Diamond players purposely throw their provisional matches so they can play against lower ranks and get like 50lp per match
playing at off hours probobly. I see alot of people higher/lower than me if I play late night.
