Seeing alot of posts about Placement games.. Let me try to explain
You were silver/gold and did well in your placements, and got placed in bronze.
I understand you're upset, but you have to realize its a trickle down effect.
Platinum is the highest you can get placed in placement matches.
that means diamond/challenger/master tier players are getting stuffed into plat.. meaning plats are going gold, gold to silver/bronze and silver to bronze.
its annoying, but as the season goes on the ranks expand and the player base finds their way back to where they belong.
