Halo infinite Trueskill 2

How does Trueskill 2 work with arena? I just got placed 6 full ranks lower than my friends because of a slightly lower KPM and DPM but I way outscored them in flags capped and ball time and captures. Is this going to be just like H5 where I am punished for playing objective and I need to just play KD to rank up? We played all 10 games together.
