14 win streak broken by people 600+ mmr under me in my promo to diamond 4 on my LAN account

gg wp'ed Did my best went 10/1/10 before 20 minutes had my adc at 8/3(he fed like shit early game [0/3 before I even cleared my second red] because he's trash but ya know them bot lanes) Just couldn't carry. Swain mid pick into leblanc somehow losing in cs when swain shits all over her. He wasn't using snare on her distort circle cause he's bad and vlad losing to cho top when all you have to do is Q and pool against him...yeah we llost to a vayne jungle. I killed her at her blue/red so she was 0/2 and then she came back.. my brain hurts.... gonna go win my promos. 2w/1L at the moment
