just looking at the defeats in recent history
the mmr seems about right
the system isn't perfect for matchmaking, it likely never will be
yes the system will try to prioritize similar ranking (both through the main system and the hidden mmr system) but it also has to fill slots for matches
I would assume it works something similar to Smite's matchmaking for ranked
which roughly follows as such
- you queue up for a ranked match
- the system searches for players within your rank range, allowing for minor variance
- x amount of time passes without a successful match find
- the system broadens the search to allow for greater rank difference
- repeat steps 3 and 4 until a match is found
