My understanding is every rank shifted up with the addition of iron tier.
So last years silver 5 is this years bronze 1. Last years bronze 1 is this years bronze 2 and so on.
Essentially, you have to be better than you were last year to get back to your old rank.
Also matchmaking is a crapshoot atm, as the system attempts to assign players across 5 roles with very little data as s9 has just started
Didn't iron tier replace bronze 5? Bronze 5 was such a large MMR (anywhere from 0 MMR to whatever bronze 4 was. 800 MMR? 600 MMR?). You could have such huge skill disparities. One person might just be building wrong items and not know how to play their champ. Another one might not even know what a cs is.
