I started the act winning all my placements but one, and i was placed silver 1. I immediately got placed in plat lobbies (i peaked gold 2 last act), and after winning my games and getting to silver 3, i've been playing in high plat/low diamond lobbies (according to their last act rank). How is this possible? I feel like i've been playing exactly like i was last act, so i don't think i got better, also because in these lobbies i've been middle/top fragging but still losing. How did my MMR increase so drastically? And also, how is it that diamonds got placed in gold/silver and not higher?
