Training / Drills

I’ve seen maps like an octagon that are used for training with pistols. How do I find that and people to train with? Float around onyx in slayer and trying to get better.

I’ve tried to find people to do this with, but more people would rather learn in MM. I wish I could of done this with others a few years back, now I’m just focused on 152. Mainly warzone. I don’t care about my WZ KD anymore. I hope you find people!
