I think Matchmaking divide into 2 queque
BR 1 2 3
BR 3 4 5
Because if they make BR 2 can met with BR 4 then they should make 3 queque
Because 2 can met with 4 but not 5 and 4 can’t met with 1
BR 1 2 3
BR 2 3 4
BR 3 4 5
Or if faulty matchmaking then
BR 1 2 3
BR 1 2 3 4 (+2/-2)
BR 2 3 4 5 (-2/+2)
BR 3 4 5
So I think the correct one is only 2 queque, BR 123 and BR 345
Tbh, the difference should be only one BR in match.
Meaning:
1 BR match
1-2 BR match
2-3 BR match
3-4 BR match
4-5 BR match
5 BR match
But I guess that’s too many queues for them. But two BR difference in match makes the BR system basically pointless.
1BR vs BR3? BR2 vs BR4? BR3 vs BR5? That’s just unfair, frustrating and not fun. Definitely not balanced in any way.
That’s why currently the only playable BRs are 2 and 5 (if you’re not planning quit matches consistently)
Since you’ll never end up facing BR that’s 2 levels higher. (And playing BR4 has no real advantage, unless you’re playing Western allies)
