On paper the Battle Rating 3 gamble seems fair:
You will be able to fight against all BRs above you, but in return you can also be matched against all BRs below you. So instead of being ± 1BR, you will be matched ±2BRs.
Now how does that actually influence the other BRs?
Battle Rating 5: will only fight against BR3, BR4, BR5
Battle Rating 4: will ALSO only fight against BR3, BR4, BR5
Battle Rating 3: will fight against all BRs
Battle Rating 2: will fight against BR1, BR2, BR3
Battle Rating 1: will ALSO fight against BR1, BR2, BR3.
With this system in place, there effectively are only two matchmaking queues,
Queue one: BR1, BR2, BR3
Queue two: BR3, BR4, BR5
Which BR profits from this the most? Its BR5 - not only because there obviously are no higher BRs, but because it has the chance to fight with BR4 AND BR3.
Which BR has the least from this mechanic? Its BR1 - not only because there are again no lower BRs, but it has the chance to fight against both BR2 AND BR3.
So to speak this BR system - thanks to the BR3 gambling + the fact that there are no BRs below BR1 and no above BR5 - is inherently bad for new players.
Now we can’t change the fact that the highest BR is indeed the highest BR - like the lowest BR can’t be fighting BR 0 since it doesn’t exist either.
But we can change the darn BR3 gamble mechanic which turns BR1 not only into a ± 1BR matchmaking, but actually into a + 2BR matchmaking.
Here is my proposal, since BR1 is the starting BR that is supposed to bring new players in - it should get its completely separated queue. BR1 should only be matched with BR1 players.
And to make sure that this doesn’t influence the matching times negatively, BR1 should start with more AI players - which will make BR1 a very beginner friendly environment, also making sure that reaching BR2 should be very very easy is essential.
If the devs want to keep new players they need to progress fast enough to unlock more powerful automatic weapons fast - while also making sure that reaching top BR gear will however take long enough to give a long time grinding goal.
Then - with BR1 being effectively excluded from the other BRs - effectively resulting in only 4 actual BRs existing, there will be no need for the BR3 gamble anymore.
