it is also a function of your actual points. for example, once you break 100k and get that free card, you'll probably stop seeing barricade L1 for example. there are a few points related tiers. (I think 4 or 5 maybe, I don't recall who worked this all out) But also its ranking itself, if you want to pull the top bosses available, you need to be inside top 250 at worst, no matter your points at the time.
