Do not allow new level 30's doing placements in promo games.
If you dodge in placements it's an automatic loss. This just allowed me being held hostage by the matchmaking system. I noticed one of our players was unranked with a huge match history of negative scores. Fair enough could be a few off games (He ended up going 0-10).
Oh well, next game will be better! It happens. Then the sum of all fears happens... that exact player got matched with me a second time. Unable to dodge I suck it up. He ends up going 0-12 this time - Apologizing the entire game for being a new level 30 and not knowing a lot of champs ability's yet.
I'm in Silver 1 promos. I want to know why both games I got the exact same unranked new player who had to vs someone in Gold each time. Both games were solely lost from him doing his placements in a skill bracket way above his.
In normals, if you get stuck in this situation you have the option to dodge. Sadly; Silver is constantly getting people in their placement games thrown randomly into your matches.
