Arena infinite streak

With this new arena hotfix update that kabam just released, the arena infinite streak method has changed. Does anyone know what the new way is? I'm talking about the 6* featured and basic arenas.

I want 30k PI opponents to have it spicy boyyy
0-10 - 3 R1 6* (worst thing you will face is maybe a team or two of R3s as you get toward the end)
11-15/16 - 3 R2 6* (you will be facing Thanos/Kang teams at 12-14)
Then once I run out of R2s I just start running my team from the top. My roster is big enough that by the time I’ve run out of R3s I have hit 12m in featured and I hit 4m in basic well before running out, so it may look different for you. But from that point you should be perfectly fine with any team of 6*.
