There is no matchmaking system in place within the lower brackets.
Games will start short, Healers on one side, groups vs solos.
Now with the recent added Talents+++ for Sync teams it just creates lopsided/stomp games.
And when did they remove this matchmaking? Just after the Experience on/off queues were un merged in BFA.
To make up for lost population? Most likely yes.
How can we get more players in the lower brackets is the next question?
Wrath Classic design team had it figured out.
